Everytime I’ve been lucid in my first REM (maybe 6 or so times within the past few months) I WAKE UP… and then it’s hard to go back to sleep.
Not so much hard just that, I stay in alphaish trances for a long time and just weave in and out of light sleep without feeling rested, until I eventually reset and go through normal sleep.
I’ve become lucid in the first REM cycle only two times so far. The first time I experienced also something alike: after I became lucid, I kept moving through intense HI and SP, while occasionally waking up for a brief time. After four awakenings I woke up completely, wrote down everything I remembered and tried to fall back asleep. It took about half an hour I guess and was pretty annoying actually. Strange…
I’ve had this ‘problem’ as well. On my holiday, I was lying awake and I tried to count myself to sleep (1, I’m dreaming, 2 I’m…etc.) after counting for about 1,5 hours ( ) I lost my consciousness for a short time and entered a LD, I woke up after at about 1 min. and couldn’t fall asleep for 2 hours. But when I slept again, I had 3 more LD’s, so i’m not complaining.
I have never become lucid in my first REM cycle before, but I have become lucid at the end of my 4th REM cycle and it has usually caused some kind of insomnia, because I keep thinking about the LD and I’m excited about it.
