Hypnogogic

I get these dream-like visions/recollections just as I am falling asleep. They seem as real as real life. But they aren't. I hope. Especially the one where I am sure I have killed and buried someone in the past and I fear being discovered. It would be tolerable, these "e;hypnogogic hallucinations"e;, I have had any waking recollections of my past. I don't. Just what my parent tell me. I am sixteen...
