What does this dream mean? HELP?

Okay, so I once had this dream that there was this circle on the wall. It shone bright white, and then started flashing to different colors. Then it turned blood red and started blinking furiously. I then woke up, for some reason I was wearing my black hoodie with the hood over my head, I was knelt beside the bed with my hands in my lap, and I had my head on the bed. I also had the dream again, exepet it stopped on dark blue, and I woke up under my window. both of the time it was 2:00 AM when I checked.
