Shift...vary how?

They seem to be very similar dreams and I cannot recall any of these occurring while I was not paralyzed. From now on, I will keep pen and paper at bedside and attempt to document as much fact I can as close to the episode as possible.

One thing that seems to trigger SP is when I sleep at a different time than what I am used to. Also, if I am coming off a night with very little sleep this seems to trigger them. What I find odd is the quality of my sleep seems to be much better when I have an SP episode, even though it wakes me up. This makes very little sense to me, other than the fact that I am obviously in a deep rem state when this occurs.
