aaaah, i have had one, i will atempt to discribe it. it was before i learned about lucid dreaming anyway, i was lying in my bed when i woke up, then started floating away, i said this isnt right, and then bam, i was back in my bed, i got up, and walked to my door, (i then started floating again) and again i was like, ggrrr! and i popped back into my bed. I woke up again and made it all the way down the hall when i started floating again. bam, back in my bed, i started to float again (by this time i was a little angry, for i couldnt wake up) this happened about 2 more times before i actually "woke up" it was weird, and REALLY annoying....
