How long does it take to enter REM sleep?
A few days I ago I had my first lucid dream that only lasted a few minutes (I think I was trying to hard to change things in the dream, which is what caused it to end early) On that day I had fallen asleep for maybe 30 minutes to an hour or more and woke up, I stayed up for a few more hours then actually went to bed. I then had a lucid dream, I was also listening to some lucid induction thing (I've been listening to it for a couple weeks now). I'm assuming you go right into a dream because your mind wants to enter REM sleep immediately.
