I was diagnosed with sleep aprea about 2 years ago and have been on cpap since. I've been reading about narcolepsy, and although my sleep study did not indicate anything about it, I find one of its symptoms prevalent in my experience. Often, I seem to dream right when I fall asleep - not after the 90 minutes it's supposed to take to reach REM. I know this is true because sometimes I'll wake up only about a half hour after falling asleep, having already dreamt. Does anything other than narcolepsy cause this? I have a slight anxiety disorder - can this cause this abnormal sleep architecture?
