A while ago, I had an experience where as I was coming out of a dream, my entire field of vision was filled with some sort of moving herringbone pattern and I couldn't move anything, yet seemed to be able to breathe and think normally. It didn't alarm me too much when it happened as I had read about SP, and I said to myself "just relax, it's normal, concentrate on waking up all the way", but for some odd reason I'm not sure if was a clear-cut case of one. As I was coming out, I found myself able to move again and the herringbone pattern gradually went away and I could see normally again. I had never read about people's entire line of vision being temporarily replaced by something like that, so has it happened to you?

I also thought that somehow I'd get 'stuck' like this and end up in a sort of PVS-like state, unable to wake up. This upset me a little, but not enough to get me alarmed as it seemed extremely unlikely, if not clincially impossible.

A combination of these experiences put me off WILD as I'm a control freak, quick to worry a lot about everything and despite the fact that I know it's all a hallucination/normal, something still is going to scare me by its mere sound or appearance, or the fact that there isn't a way to just simply stop if i get afraid or alarmed.

Was this SP? And can I really get 'stuck' like that?
