Almost lucid, again!

Some of you may have read my previous post about me almost becoming lucid but awoke my self cause I was a pansy :banana: but last night things changed. I became lucid and I remember thinking about whether I want to go through with it, and I proceeded. I remember trying to begin to float (I remember reading somewhere that you can float), I rose from the sofa I was actually sleeping on by a few feet I think, but the air\atmosphere was rediculously noisey :?, I remember it being painfully noisey which after a few seconds awoke me. I hope it's not like this everytime. Better luck next time?
Anybody experience the same thing before?
p.s. oh yeah I remember my vision moving up and down very fast(almost like when u wheel spin in your car), guessing that was from the rapid eye movement?
Cheers
