I have been having vivid horrific dreams every night since I was very little (as in maybe 5-6) years old. They soon started to not happen as much. I am now 17 years old, and they've came back with even more horrific things than I've dreamed about before. It's happening every night, again as it has before. I don't see any scary movies or previews to any. I don't read any scary books. Nothing really severe has happened recently to make them happen. I don't know what could be causing this! PLEASE HELP!!
