I can see where OP is coming from. I can't get into SP to save my life. I would loev to have a vampire sitting on my chest, but I just can't get it.

So I think the original question is still unanswered. Does SP only happen with the onset of REM, or with the onset of sleep itself? Meaning, if we were to try to WILD at the beginning of the night, would we reach SP (not the lucid state, just SP) at the same time we would usually fall asleep? Or would we have to wait til the 90 minute mark REM phase to start?
