Tonight I did an experiment. I stared at myself intensely in the mirror and imagined the being in the mirror as a separate being from myself that I created.  I had a sudden intense sensation and the being in the mirror started to get darker and I literally saw a flash of an incredibly evil being staring back at me. I quickly turned away because it terrified me so much, so who knows what would have happened if I kept going deeper. Has anyone else had a similar experience? Is this all in my head, or do you think I really saw what I saw?  Just to clarify, I wasn't on any psychedelics or drugs of any kind. It was during normal consciousness, but it felt like I entered a slightly different state of consciousness for a brief moment.
