thanks guys, thats reassuring then (at least i know others are getting the same thing happening)
well last night i had another experience, will try not to bore everyone with it but someone else may read it sometime and think "Ive had that too"
last night i was in bed, (laid on back, arms down by side, hands touching mattress) eyes closed, focused on breathing, the funny thing was the eye flutterings were about to start and i just smiled and thought bring it on...... but they didnt! i remained calm, it got to the point of i couldnt feel my arms at the side of me and i kept asking myself "are they still on the bed" (i literally couldnt feel them as if they were an inch off the bed) and my body felt SO light ! i just kept smiling to myself thinking trust, see what happens ive got protection, then i had all images floating around and towards me the same colour indigo/purple kept appearing, and if they were faces coming towards me i couldnt work them out, i just kept having to reassure myself to stay calm dont be scared and just see what happens.....
it all died down and because i was so curious about if my hands were actually laid on the mattress i kind of brought myself out of it (and yes my hands were on mattress laid flat as i started) my whole body just felt so light.
again i dont know if this is normal behaviour so if people can enlighten me, i dont know if ive taken another step forwards or what but it was a different experience for me :-)
