Last night, right after going to bed, I began to see black spots in my vision. At first I thought they were some sort of weird eye floaters, and I ignored them. Then I began to see more and more of them. They sort of swirled together into an opaque sphere roughly the size of a baseball right in from of my face. At first I thought, "I'm not really seeing this, am I?" Then I thought I must be dreaming, but I didn't feel like I was sleeping, or even half awake. After that, my thoughts could best be described as, "Oh BAD_WORD, I'm awake and this is really happening!" For a few seconds I just wondered what to do. Then I freaked out and sort of attacked it with my blanket. I remember saying the word 'please,' as in please go away, please let this not be happening. When I lifted my blanket, it was gone. I was seriously shaken, mostly because I don't believe in this kind of thing, but, oddly enough, not really frightened.
Anybody got any idea what I saw?
