Well that was odd...

Strange phenomenon I have never experienced before...

Last night, half asleep, I became aware of watching the inside of my eyelids. Shadow and light moved as one might expect, but in the lower half of my vision was a much darker semi-circle, the arc upward towards the centre. When I breathed in, the dark semi circle expanded. When I breathed out, the dark semi circle contracted and  I could see lighter grey-white rippling outward from and across  the base of the semi-circle like little waves. It was really weird, I am pretty sure I was awake.

I tested it a bit, it faded after a while. Wish I had thought to open one eye,see if there was any difference.

I wonder what it is?

In better news, I am getting over this lurgy. Back to work first thing Monday morning.
