This has happend to me also, it's as if though i am awake but asleep at the same time, i see the dream state coming on but i'm not yet fully asleep. lately though it feels like something is pulling on my arm. i take baths now with espom salt (magnesium sulfate only) lavender, Sleep, and it has worked fairly well, i get at least 5 to 6 hrs of sleep, if it's a good night i'll knock out 8 to 9 hrs
