I awoke with a start, puzzled. My bedroom was lit only by wisps of moonlight that shifted ephemerally with the fast-moving clouds. There was a deep and brooding silence, expectant, like a held breath. I could see no one else in the room, yet I felt eerily like I was being watched. I tried to turn my head to look at the clock on the nightstand, but I couldn't; no matter how hard I strained, I couldn't move.
On the edge of my vision there was a slight movement, just a quick blur to my right. I tried to look over that way; I could see nothing but the curtains fluttering slightly in the summer breeze. Then...
There was a patch of darkness, like a square of night that seemed denser, a deeper black than the rest of the shadows in the room. Suddenly it moved away from the window and began sliding up the wall. My heart was pounding as I watched it flow up the wall, then across the ceiling until it was directly above the bed. It seemed to flex and move, almost to pulsate like a beating heart. It was growing, spreading, like a dark cloud. Then, to my horror, I realized it was beginning to sink toward me.
I strained against whatever was holding me in place, in vain. I tried to scream but all that came out was a terrified whimper. I didn't know what the hell was going on, only that the experience was scaring the shit out of me!
A deep and icy coldness spread over me as the cloud dropped over me. A pressure was on my chest, like a stone beginning to crush me. The cold and the weight spread over my entire body, making me numb.
Suddenly things began to change, I suddenly began to feel tingly all over. I could feel my nipples begin to harden beneath the silk of my chemise. There was nothing remotely arousing about the situation, yet I was beginning to feel horny.
