Sounds pretty disturbing...
I had one that really back last fall. Meant to post it in the dreams thread but forgot.
In the dream I was looking in a mirror and admiring myself. A feeling of what I thought to be love flowed through me. I thought "Why not? If anyone deserves my love, it's definitely me." I decided to hug my reflection, dropping to my knees on the floor and wrapping my arms around the mirror. I turned my face to look at the eyes of my reflection. They were cold and dead. There was no love in them. There was nothing. Empty.
I scuddled backwards on the floor to get away from it, but the eyes of my own reflection followed me and the reflection itself did not mimic my actions. It just sat there coldly staring with dead eyes. I could not avoid it. I thought to myself that this couldn't be me, this corpse-like thing I was seeing. The reflection sat unmoving, unfeeling and just staring. It was dead, empty and there was no way to escape it.
