I saw a human like figure when my eyes were closed?

The other night I shut the light out to go to sleep on the coach, and I was facing towards the cushions, and it seems my mind was concentration on something unusual, and I briefly saw a shadow of a person or something that looked like one. I don't know who it was, or if my mind was playing tricks on me? I immediately opened my eyes and was a little freaked out by it. I turned the television on, so I could fall asleep with that on. I know I wasn't hallucinating. I don't do drugs at all. I have a little depression and some anxiety issues which I have been getting help for, but I'm not on any medications at all. It's just weird. What is my mind doing and who did I see? It's also weird because every now and than at night before I fall asleep, my mind is working differently and trying to do something or get into another part of my mind. Is this how people like dream of things that will happen in the future. I never have, but my mind is working differently and uniquely. I'm not crazy, but maybe it's just my anxiety issues or I'm thinking too hard. Any information about the mind will be helpful. When I'm asleep, I don't see anything, it's only when I'm in a deep rest with my eyes closed and still thinking, and I'm not asleep.
