SP?

I remember vaguely waking up this morning for about a minute before drifting back off to sleep. Anyway..

When I woke up, there was a strange feeling in my legs. I didn't see any HI but it took me a while before I could move my legs again. I had to think about moving them before I actually could move them.

Was that SP, or extreme tiredness?

you don't have to have HI or anything for it to be SP. Sounds like you might have had it. Next time use it to become lucid.

Yeah, it was probably the early stages of SP
