I've had sleep paralysis, it's not unusual before an OBE.
Tell me Rem, are you one of those people that believe there is a 'perfectly logical' explanation for anything out of the ordinary? If so, I would use an old saying, "To anyone with faith, no proof is nessasary, for anyone without faith, no proof is enough." I give you first hand experiances and you reduce them to fit your small beliefs.
Thank you Donkey LOL...OUCH!
