A couple of nights ago, i was trying to do a WILD. I failed, because i fell asleep and didn't hold on to awareness. Anyway, i had a dream, and after i woke up from the dream, i tried to move. I was in the middle of rolling over and for some reason i had my mouth open, and all of a sudden, sp kicked in. I wasn't expecting it, because i thought you had to be still for sp to kick in, but i was in the process of moving. I was caught there, with my mouth half-way open, in sp. I tried to use this opportunity to try WILD again, but the sp faded away and i was back to a normal waking state.

My question is, is this normal and has anyone else had sp to hit them while moving?
