Occasionally, when I turn the lights out to go to sleep, I see strange shadows. I'll be lying in bed looking at the ceiling, and shadows will for from nothing a swirl around and make patterns or shapes/faces. It's so strange to me because it usually takes me about an hour to go to sleep, and these shadows usually appear 5-10 minutes after I turn the lights off. I feel this is too early for any HH, so is it perhaps an eye problem or just my mind turning to mush.
