I've never understood, why does I rarely see dream's. But I noticed, that when I do not consume for days, all those dream's that I've collected all that time, just pours over my head while sleeping totally sober. I have never paid attention to this tho. Till one day, I was watching some of Joe Rogan's podcasts and found the one with Matthew Walker, a Professor of Neuroscience and Psychology at the University of California, Berkeley, and Founder and Director of the Center for Human Sleep Science. Who also wrote a book called "Why We Sleep". Then all became clearer...

I've also done an experiment on myself, when I still vaped microdoses in the evenings, but at least 4+ hours before going to sleep. I've noticed some improvement of my REM sleep, if I don't do it right before going to bed.
I wonder, how it affects yours ? It's interesting, because we are all individuals with different habits and genetics.

Let’s discuss the effect of the drug on sleep. It has been proven time and time again that cannabis effectively prevents dreams. Some people even profit from this effect, using the drug for the prevention of nightmares. This happens because the drug strips away a considerable portion of a user’s REM (Rapid Eye Movement) sleep, which is the stage linked to dreams. It should be noted that the scientific community also does not know the reason behind this phenomenon.
Now, let’s discuss the importance of sleep. It has been observed in many studies that REM sleep plays a crucial role in cognitive function and memory consolidation. It is too great of a coincidence that those are the precise qualities that are harmed by marijuana use in the long run.
The book Why We Sleep, by Matthew Walker, PhD, highlights some of the essential reasons for sleep in general, and covers some important topics that will be crucial for the understanding of why cannabis affects the brain. In the book, Walker mentions the interesting hypothesis that dreams are a mechanism of the brain to strip away the sting of painful memories over time, thus preventing trauma. He has also observed that individuals who suffer from Post Traumatic Stress Disorder (PTSD) seem to have a deficiency that prevents them from having proper REM sleep. This deficiency is characterized by a failure to bring down norepinephrine levels during REM sleep. It has long been known that a defining characteristic of REM sleep is a sharp decrease in the levels of norepinephrine (usually referred to as the fight or flight neurotransmitter). To Walker’s surprise, another researcher had found a blood pressure drug that had an interesting side effect: it inhibited norepinephrine. Walker, now given a way of testing his hypothesis, soon began trials of the drug on PTSD patients. The results were promising, it seemed that the blood pressure drug was indeed capable of helping individuals with PTSD.
But how does this tie into the subject of marijuana-induced cognitive and memory impairment? The answer is simple, the drug is known to highly increase the levels of norepinephrine in the brain. With this information in mind, I have taken a further step from Walker’s theory and hypothesized that a lack norepinephrine plays a critical role in proper REM sleep. If marijuana increases the levels of norepinephrine, it inherently decreases the amount (or quality) of REM sleep. The pieces of the puzzle started coming together. Low norepinephrine levels are important for proper REM sleep. REM sleep is important for cognitive function and memory consolidation. Marijuana increases the levels of norepinephrine. The increase of norepinephrine caused by cannabis, therefore, must be the reason why marijuana inhibits REM sleep, and the lack of REM sleep must be the reason why a long term impairment in memory and cognitive function is observed in heavy users of the drug.
The procedure was simple, we were to test my Dutch friend’s sleep cycles through a readily available app (called Sleep Cycle) during nights in which she was sober, then on marijuana. Here are the results:

Sober Night
Sleep on Cannabis
Those two graphs show her sleep after using only cannabis. Notice how there is a great amount of deep sleep (which doesn’t necessarily mean REM sleep) earlier into the night, but then she goes into lighter sleep stages and does not go back into deep sleep.Source
