Dreamers Plague

The newspapers are full of unexplained murders taking place everyday. It seems the phrase, Serial Killer, is used to describe some of the various types of murderers who commit these hideous types of slayings.
When their killing finally ends with the police catching them, what are some of the excuses these criminals use? A voice told me to do it; God spoke to me, and said I must do it and the all time favorite,
Aliens from outer space are beaming their thoughts at me. I was only protecting myself.
Dreamers Plague takes this and asks, what if it was true? What if there was someone sharing your thoughts, or a voice that really spoke in your mind? What if, night after night when you went to bed, you shared someone elses dream?
Now suppose that youre the one sharing the dream, and you became a part of their nightmare. You could see through the others eyes, feel what the others persons hands touch, every emotion they have you have.
