I know what I am about to state seems lame. It actually worked for me. You see, when I was 20 something, a guy played russian roulette with his pistol in my car as a passenger in my front seat. There were two others in the back seat. As I drove, he placed one round in the chamber, twirled the chamber and clicked it on my side ribs. He clicked it twice to his best friend, once to another friend, once outside then, once to his brain and BLAM! He shot himself with blood, and brain matter splattered all over the side of my passenger door, I know this because I had my girlfriend clean it up afterwards. I couldn't bring myself up to cleaning this up. I will not tell you why this awful scene occurred. I have a hard time just bringing this up here. I am bringing this up to help you. I kept seeing his ghostly image in my room at night as I slept. He kept wanting me to come with him. I would not. So, I was walking in a Mall one day, and I passed by a kiosk vendor selling "Dream Catchers." I chose one about 6 inches in diameter, bought it then, hung it up on the ceiling with a tack, but hanging down above my head as I sleep on my bed. This worked. I have not had a bad dream nor, nightmare nor ghostly visitation as I slept, since. My old one, gathered much dust and withered away from years of hanging. I bought another one. I have lived in various towns at various apartments. I have always had one above my bed. The Dream Catcher has always worked for me. I bought one as a last resort, and I guess I sort've believed on it because I stated as I hung it up; "I hope this works, I really need you to work for me."
Anyway, Blessed Be.
