All my Nightmares

I am startled awake by something inflating suddenly and rapidly underneath my pillow.

Looking up, I see on the wall above the headboard, a flashing and sparking piece of electrical equipment, crackling and buzzing. It may in some way be connected to whatever has inflated under my pillow.

Ants have invaded the bed. They are swarming under the bedclothes. I can feel them running over me. They may actually be spiders.

Outside the window, presumably on a ladder, a man is looking in, impassively.
