That's a rare event indeed! Its probably happened becuase of the odd time you boarded, they say a disrupted sleeping pattern can cause SP.

I had another experience the other morning with lots of 'hags'. I was having a really awesome dream and it was starting to fade on me, it felt like I was waking up. My whole dream fades to a sunny bright white (the sun does hit my room in the morning, so i think natural sunlight did bleed into the dream). I feel a weird dizzying pressure all around me, actually it felt more like really bad vertigo. At the same time I found myself on a blinding white bed in a blinding white room.

Everything was blinding white except for the shadow beings standing over my bedside. At first I was scared so I tried to wake up. But i couldn't move or force myself awake so I felt pretty much stuck there. And the room still kinda feels like its not stable? I tried to think rationally what's the best thing to do now. I figured the shadow beings must be dream characters so maybe if I thought of them as friendly...then they'll be friendly? One of them comes even closer, standing right over me.

I ask him to help me up! I offer him my left palm, get me out of this bed! He grabs my palm, digs his claw in my skin and then tries to bend my fingers backwards. Needless to say the pain snapped me out of it and I was finally awake (so i guess he was helpful, lol?). Fail! I realized they were dream characters but I didnt consider that I could just close my eyes and enter a dream scene.

And I'm mostly typing this out so I can remember next time.....
