I was walking home from High School when I stopped to check out a strange event. A mailman entered a house. It had a large front porch and a high yard accessible by cement steps. Moments later the man fled from the house; crazed, screaming, flailing his arms above his head. Curious, I entered; went upstairs to a bedroom and saw a man sitting cross-legged on a bed. He was dressed like a Ghandi and was just as emaciated. He put both hands into his chest and pulled it open. Where the heart should have been was a mass of blackest black; pulsing and musilaginous. I ran. When I got home the front wall was missing and the interior of the house was exposed. I ran down the driveway to the back of the house; jumped the fence into the neighbor's backyard, and followed the fence to the street. Across the street was a mini mall ( I recall a store there. It was called Zayre or Zayres.) The parking lot was almost empty, but I saw a white, Goddwill donation booth; one of the tall ones with a walk-in door. I ran across the street and entered the booth. I walked forward along a white hallway until I came to a right turn. In the corner was a cleft big enough to squeeze into. After turning right and continuing forward, I passed a water fountain set in the wall on my left. Then voices came from ahead; and I fled their approach. I returned to the cleft and pressed myself inside, working myself as far in as I could in a conch-like clockwise direction. When the voices passed, I followed them outside. There was an enormous crowd in the parking lot; I could barely push my way through the crush. When I could turn and see, the freaky man with the trick chest was sitting cross-legged atop the Goodwill booth. He was preaching to the multitude, and they were eating it up. I pulled a small hand gun, took aim on the man's forehead, and just as I began to squeeze the trigger, I awoke.
I have also had similar dreams about demons. Just as I go to confront the demon, I awaken. I have had dreams where I fire small handguns at demons, chop off their heads with swords, etc... The most important thing, is that you confronted the demon. I don't think you will be seeing that mf'r again.
