yeah that was it. it kinda sucks with the visions though. One time when I had it i saw a mirror of myself lying in bed, and there were four people dressed in all black choking myself, and reflection of me died.....sucked. But that was before I learned about relaxing and whatnot. Normally when I have SP, and I wake from it, if I attempt to go to sleep right after it happens, it'll kick in again, and this was back when I didn't know anything and was trying to fight it. So the next time it happens, and you wake up, try going back to sleep without doing anything.
