Is it true it takes 3 hours to meditate and be in the zone to be able to be out of your body feeling all light? a guy at work told me you need to be in the zone and meditate for 3 hours. I tried for 30 minutes and all i got was feeling weight pulling me down (sleep paralisis(sp)?) on my bed.

Also, he doesn't know what the problem with my eyes are but at times my eyes like to force open. Doesn't happen all the time but several times in the 30 minute meditation my eyes kept trying to force open, aswell as move side to side really fast. How do i get rid of that?
