How I tell of increase in REM sleep (x): 1. Remembering some dreams in the morning. Especially that I dreamt right before waking up. 2. Calmer mood, less jittery, harder to irritate. 3. Easier to maintain focus on things that are not fun, easier to resist distractions. How I tell the level of cannabinoids/alcohol in the body fell enough to allow good sleep with both deep and REM phases: - The first night you sleep with a proper REM phase you get a REM sleep rebound. It's characterized by lot of vivid, intense, often rare dreams. Easy to notice after a period in which you pretty much don't remember any dreams. Happens because there is much pressure in the body to catch up for lost REM sleep, but rebounds are not enough to catch up. The sad and deeply diabolical thing about cannabis is that it's half time in body is quite long (though adapted bodies metabolize it faster), so smoking/consuming chronicly (defined in Huberman Lab as 2 times per week or more often) is enough to pretty much completely rob you of REM sleep. You can't remember any dreams and even worse, you loose your everyday free emotional therapist that is REM sleep. If you add some other negative experiences or just a difficult period in life, you're in for depression or at least sad/tired/boring days. And what you might escape into in these days? Often more weed. x: anecdotal, most likely influenced by huberman lab's episodes on marijuana and on sleep. They describe what roles both deep sleep and REM sleep perform. Episode on weed is a must - listen for people consuming cannabis in any form, even sporadically, because lot of things around cannabis are counter intuitive (f.ex. that it doesn't help with sleep). If you thing problems with sleep affect you or that your sleep quality suffers because of drug (including alcohol) use, consider listening to these Huberman Lab episodes or talking to a specialist if that's available to you.
