Maybe I've simply never paid attention, but I've only experienced SP when I'm trying to wake up... never while falling asleep. Also, if I'm in a LD, I can be aware of my physical surroundings and I'm not having SP.... like one night recently I knew that my throat was dry and I wanted a drink, but I didn't want to wake up from the LD. Eventually it was making me crazy so I thought (stupidly) that maybe I could reach my water bottle and drink and stay asleep, and of course I woke right up from moving. Is this normal? Or am I misunderstanding SP?
