Well it can also be the case that I just have a very good dream memory, but I noticed that I can relatively easaly drift into a dream while being aware of my environment even when I was fully awake before. Not always though.
I also can remember having 4-10 dreams in a night. Of cause we don’t only dream in the REM sleep so it’s kinda hard to keep track of how much I actually sleep.
I probably just have a pretty good dream memory and have a very light sleep
