Okay, this one is really weird. I had slept late, as usual, and was about to get up. I was lying on my side, facing the bureau on the opposite side of the bedroom. I caught a flash of a pinpoint width of blue light, and thought at first it was my eyes acting up again. Then it happened again. I stared at the bureau trying to figure out what was flashing. We all know by heart the contents of our bureau tops and I knew for a fact that there was nothing up there that should be flashing.
I watched for it to happen again. This time, I noticed that the flash of blue light was at first preceded by a small, slowly growing square of light; it was dim at first, then seemed to get brighter, then the blue light would flash; a lot like when a picture is taken. The only thing that has a flashing light in that room is a smoke alarm high up on the wall on the same side as the bureau. And the only electronics in the room are the cell phone charger, which is kept plugged in and does not flash. There are two lamps, and the mini split high on the wall opposite the bureau and it does not have any flashing lights, either.
I finally approached the bureau. The light seemed to be reflecting off of a round, metal container meant to hold potpourri. It has tiny holes all over it, and I keep my crystals in there. I moved it over just a tad, and then watched for flashing blue light to happen again. It did not. I haven't seen it since. Weird, huh?
PS: This happened around 11:30 am on August 15th.
