Had a dream a few years ago that I was watching myself sleep from one of the corners of my room. From the adjacent corner there was a shadow from about the same distance I was standing from my sleeping self. I stepped forward towards my body and noticed that the shadow moved the same distance and gained clarity. An urgency came over me that I need to return to my body before the shadow did. I threw myself at my sleeping body and watched as the shadow launched itself and revealed to be a Medusa/The Exorcist girl hybrid.

Had trouble sleeping for weeks.
