The Impact of Cannabis on REM Sleep and Mental Health: A Personal Reflection

2/5/2026, 9:50:17 PMMale25-34

Since the age of 17, I have relied on medical cannabis to help manage various aspects of my life. Now at 26, I’ve begun to observe distinct changes in how my dreams manifest as my consumption habits have evolved. In the past, I frequently experienced lucid dreams—these were vibrant and allowed me the freedom to explore different scenarios and connect with specific individuals while I slept. I vividly remembered these experiences upon waking. However, with the introduction of cannabis into my nighttime routine, my dreams have significantly diminished, often surfacing only briefly at the end of a full eight hours of slumber, or not appearing at all. Additionally, recalling these dreams in the morning has become quite difficult. Interestingly, I’ve found that if I manage to nap for an extended period of about 90 minutes or more during the day, my dreams can be strikingly vivid—perhaps even more so than in my pre-cannabis days. While I understand that cannabis may have repercussions on memory (thankfully, I haven't noticed any adverse effects on that front), I am curious about the long-term implications on my mental health. Specifically, I seek insights into whether regular use may heighten the likelihood of conditions like dementia, Parkinson’s disease, or challenges with emotional regulation. Moreover, I would appreciate a detailed explanation of the underlying mechanisms at play. Feel free to use medical terms; as a healthcare professional, I'm eager to hear from experts in neuroscience or neurosurgery regarding this matter.

Your reflection on the effects of cannabis on your sleep and mental health is insightful, and I appreciate your curiosity about these experiences. It's important to understand how cannabis might be influencing your REM sleep pattern, dream vividness, and long-term mental health.

Key Points:

  1. Cannabis and REM Sleep: Cannabis use, particularly strains high in tetrahydrocannabinol (THC), is known to suppress REM sleep. This can lead to fewer dreams and less recall upon waking.
  2. Impact on Mental Health: Regular cannabis use is associated with mixed outcomes concerning mental health and neurocognitive risks, particularly if used frequently and from a young age.
  3. Mechanisms Involved: Cannabis affects the endocannabinoid system, which plays a role in regulating sleep, memory, and mood. Disruption of this system can influence neuroplasticity and may have implications for conditions such as dementia.

Explanation:

  • REM Sleep and Dreaming: REM (Rapid Eye Movement) sleep is the sleep phase most associated with dreaming. THC can decrease the amount of time spent in REM sleep. This is likely why you’ve noticed fewer vivid dreams.
  • Vivid Daytime Naps: Your experiences during longer daytime naps might be associated with entering deeper sleep cycles or a different balance of sleep stages, allowing for more REM periods when you're not under the influence of THC.
  • Mental Health Aspects: Regular cannabis consumption may contribute to anxiety or depressive symptoms in some individuals, particularly with high-THC varieties. Concerns about conditions like dementia or Parkinson's disease are still being researched; however, current evidence does not conclusively establish a direct link between typical cannabis use and these neurodegenerative diseases.

Next Steps:

  1. Assess Your Consumption: Reflect on how your cannabis use aligns with your mental health goals. If your primary goal is to enhance dream quality and recall, consider moderating your use, especially close to bedtime.
  2. Sleep Hygiene Practices: Incorporate practices such as maintaining a consistent sleep schedule, creating a calming bedtime environment, and minimizing screen time before sleep to promote better sleep quality.
  3. Monitor Your Functioning: Keep a journal to note changes in your mood, dream patterns, and overall cognitive function as you make adjustments to your cannabis use. This can provide valuable insights into how these factors interact.
  4. Discuss with a Professional: Consider discussing your experiences with a healthcare provider who specializes in sleep medicine or mental health. They can offer tailored advice based on your unique circumstances.

Taking these steps can help you manage your use of cannabis in a way that promotes your overall mental health and sleep quality while allowing for continued exploration of your experiences with dreaming.

Experiencing Headaches After a Sandwich: Is There a Connection?

As a 30-year-old woman standing at 5 feet 5 inches tall and weighing 133 pounds, I’ve found myself pondering the mystery behind my recent headache. In the past, I indulged in the questionable choice of consuming three Big Macs in one sitting, which clearly led to a monumental migraine that felt as though it might blind me. It was a harsh reminder of the repercussions that can come from such extravagant eating habits. Lesson learned—I certainly won’t make that mistake again! However, today, I enjoyed a seemingly harmless sandwich from Jimmy John’s, yet somehow, I was greeted with a similar headache (though slightly milder). This has me scratching my head. Could it be that an excessive amount of sodium is once again to blame? I’m looking for insights—any thoughts on why I might be experiencing this recurring pain?

Hormonal Imbalance Concerns?

I am a 29-year-old woman with Northern European heritage. Medical History: I have been diagnosed with Major Depressive Disorder (non-psychotic type), Generalized Anxiety Disorder, ADHD, migraines, hypersomnia, GERD, IBS-D, mild asthma, iron deficiency anemia, and a benign right ovarian cyst (diagnosed in November 2025). Additionally, I have a history of gallbladder failure (with a cholecystectomy performed years ago) and benign arrhythmia. Current Medications (taken daily): I am prescribed Fluoxetine 60mg, Cetirizine 10mg, Famotidine 20mg, and Norgestrel 0.075mg. I also take viviscal (a supplement for hair growth) and Calm Aid (Silexan lavender oil) twice daily, which were recommended by my psychiatrist based on recent research and his personal evaluations. For much of my life, I've experienced such a low libido that I've questioned whether I might be asexual. However, a few months back, everything shifted. Suddenly, I found myself constantly feeling aroused, which on its own could be merely a change in personality. Yet, this was soon coupled with persistent pain in my lower left abdomen, increased facial hair, intermittent migraines and vertigo, faintness, hot flashes, and irregular bleeding, despite being on birth control that previously managed my periods. By late October or early November, the pain in my abdomen escalated to the point where I decided to visit the emergency room before heading on an international trip, worried that I might face a critical issue abroad. I suspected the presence of a cyst or fibroid might be to blame. The CT scan results were normal apart from a slight bone deformity and a benign cyst on my right ovary. It was quite a revelation. Months later, I still experience the same abdominal pain alongside all other symptoms mentioned. I am currently seeing an OB/GYN who has not reviewed my medical records or allowed me to fully discuss my history. He dismissed the possibility of PCOS since I don't exhibit the classic signs (notably, I pluck my facial hair instead of waxing) and congratulated me regarding my increased libido. When I inquired about changing my birth control, he warned that it might exacerbate my migraines. He referred me for a pelvic and transuterine ultrasound. Although the ultrasound is complete, I now wait anxiously for the results. The only detail I could make out on the screen was that my uterus and ovary appeared elongated. In the interim, these issues significantly impact my work and daily life. I am keen to hear if anyone has suggestions for alleviating the symptoms or insights into what might be causing them. P.S. I am certainly not pregnant - I believe the ultrasound technician would have informed me of such. Additionally, I have never been pregnant and am free from STIs.

Understanding the Complexity of My Symptoms: What It Means for My GP Appointment

Greetings! I hope it's okay to bring this up, but given my experience as someone on the autism spectrum, I'm feeling quite confused about my recent consultations. My challenges in interpreting social cues only exacerbate this situation. I made a conscious effort to schedule a visit with my GP, intentionally opting to wait longer for an appointment with a highly regarded physician, an experienced gentleman known for his meticulous approach and extensive knowledge. During our meeting, I detailed my various symptoms, and to my surprise, he suggested collaborating with a neuropsychologist and considering an MRI, stating that my symptoms are too intricate for a straightforward diagnosis. Now, here I am, left in a holding pattern, wondering what this truly signifies. Does this imply that whatever is affecting my cognitive functions to the extent that I struggle greatly with daily tasks cannot be remedied by standard medications? Could it indicate the possibility of a more serious underlying issue? I recognize that a conclusive diagnosis may take time, but I'm eager to glean some insight from you all. What do you think tends to be implied by the phrase "too complex for the foremost GP in your vicinity"? Am I overthinking this, or could this be a hint that I should adopt a more serious outlook regarding my health rather than dismissing it? I would appreciate your interpretations as I navigate through these uncertainties.

Is Homeopathy Ineffective or Could It Be Dangerous?

I’m 21 years old and female. I recently had a blood test indicating a TSH level of 10.24, while my T3 and T4 were normal, which leads me to believe I have subclinical hypothyroidism. I’m hopeful this is a temporary situation. My mother has suggested I try some homeopathic remedies. To clarify, I am skeptical about alternative medicine; I’ve always viewed homeopathic treatments as extremely diluted mixtures that are ineffective but harmless. Although I don't believe they are beneficial, I’ve tried to remain respectful and acknowledge that I’m not a healthcare professional, so I’m out of my depth here. Whenever she offers them to me when I’m feeling unwell, I typically decline. However, seeing her so worried about my test results prompted me to agree to try the remedy she recommended, which supposedly helped my cousin with subclinical hypothyroidism. When it arrived, I planned to look up its name and see what claims were made on the brand’s website, hoping I might still experience some benefits from the placebo effect, if nothing else. Upon receiving the medicine, I was immediately concerned to see the term "Thyrotoxic" in parentheses on the packaging. When I voiced my concerns, I could tell my mother was annoyed. Curiosity led me to further investigate, and the website indicated that synptoms like hand tremors, sweating, bulging eyes, weight loss, and diarrhea could be associated with hyperthyroid conditions, also known as thyrotoxicosis. I was taken aback—my issue seems to be the exact opposite, and I currently do not experience any of those symptoms. When I shared this information with my mom, she countered with a question about my elevated levels. I attempted to clarify, albeit with limited knowledge, that high TSH suggests insufficient production of thyroid hormones, rather than an overabundance. This treatment seems aimed at the contrary issue. If it is effective, wouldn’t it exacerbate my condition? Am I misinformed in thinking this way? Whenever I bring up concerns like these, she often admonishes me for indulging in negative habits that affect my mental wellness. To be clear, I don’t obsessively search for every potential side effect of what I consume; however, I do believe it’s prudent to read the labels on medications and supplements being recommended to me. Further research led me to a study on PubMed that discussed how some homeopathic products have been found contaminated with steroids, which troubled me considering I’ll be undergoing a follow-up test soon to check my TSH levels. I’m starting to view this homeopathic remedy as potentially hazardous rather than the benign solution I initially thought it was. Despite having previously stated I would avoid homeopathic treatments, I find myself questioning their true nature. Are they really as harmless as claimed, or could they have negative implications for my health and test results? Should I compromise and take this medication merely to appease my mother? As an aside, the product’s ingredient list includes: Atropinum 8x, Hekla lava 8x, Iodium 4x, Spongia tosta 4x, Bromium 6x, and Natrum muriaticum 8x.
