I have 2 more to add to the chart. When I wake up in the middle of the night, I can see patterns, flashing on and off rapidly. The pattern is almost the same thing every time. Hard to explain, but I can draw it. Also sometimes I wake up in the middle of the night, and get a rapid speed slideshow of images one after the other that is very dim, but noticeable. I mean it goes really fast like you were looking at slides in rapid succession. Almost like a "download" of something. I get the impression that is exactly what is going on. Sometimes I can get the rushing sounds but thats just the sound of my ears flexing into a sleep position. Usually hear it while coming out of sleep or going into it. I also can sometimes hear myself start to snore.
