I saw strange flashes of light last night in a dark room and am wondering what caused them. They seemed the only happen when I moved the comforter, but it was not always in the same area. I thought at first it was a brief reflection of light, but I couldn't find a source for the reflection that would have matched. I also considered that it might be some sort of static energy. I have no idea if static energy is visable as sparks in the dark or not, so that's why I'm posting here. I don't know if this makes a difference, but I had just put the sheets/duvet covers back on the beds after being washed, so there almost likely was more natural static energy present anyway. Also, I saw them both in my sons bed when putting him to sleep and in my own bed when I woke up randomly at 3am. Insight appreciated!
