Back in the 1960's I use to see all kinds of non-existent things also. Once I saw Mr. Budweiser come right out of the bottle and chase me around the room. I miss those days, lol.
Jloring, I once saw the devil sitting across the camp fire from me. Eventually he turned back into my buddy.
Sounds like you saw some very light green, with maybe some purple and orange highlights to begin with. Nice & kind?
