I have been experiencing this phenomenon for 15 yrs and yet I'm puzzled by this 4 ft figured gray creature of the night. I have seen this several times, but not with in the last year or so. Instead I awake to find the room cold or even a tap on the shoulder. Once i could of sworn my bed was shaking violently. Or maybe i awoke suddenly and it startled me, I dunno. But in do respect. I'm usaualy not quite alseep when this occurs. NE 1 else have this strange problem????
