You dream all night. The trick is to remember it in the morning. Carlos Castaneda said that the way to have a lucid dream is to try, during dreaming, to remember to look at your hands. If you can do that, you can start to move your hands and then you take over the dream. ‘Course Castaneda was a mid-70’s UCLA drug addled hippie.
True, but he was also right about a lot of stuff.
I thought people only dreamed while they are in REM (rapid eye movement) just prior to fully falling asleep or fully waking up.
That’s been my experience. I think.
