I'm just curious...does anyone else occasionally see strange symbols upon waking up in the morning before your eyes are open? This happens to me off and on. They are very plain, but only last for maybe 15 seconds or so and then dissolve. I seem to remember in college psych class that it was mentioned that 15 or 20 percent (?) of people sometimes see geometric figures before their eyes upon awakening, but these were described as more like geometric grids or patterns. The symbols I see are more like letters.
