For the last few weeks, I have been having a rather odd experience. There will be a sudden flash of white light as if someone in an adjoining room had taken a picture with a flash on their camera. This will happen when I am alone or at night when I am in bed reading and know exactly where my wife is because she is sleeping there beside me. Thre is no sound associated with it and if I go to look there is nothing to see. No light that was on has gone out and none that were off have turned on. I am 100 yards back off of the road in front of my home and live on 3 acres that are fenced with an electric gate in the front so I know at night it isn't a car turning around in my driveway. Since it has also happened in the day that wouldn't apply anyway. I don't think for sure that this is a paranormal thing but then I'm not sure what is causing it. Could it be some sort of ocular disturbance like floaters? I don't know but am wide open for suggestions.
