It happens to me whenever I take a nap..
It's easier on naps...
what's happens is like this:
I relax a lot...lose the consciousness for 2 seconds..and then I recover it...on my black eyelid instantly appear a fragment of an image(that means that it doesn't cover all of my sight)and when I look at it...it goes away =(
would be great to maintain them...and see what happens...
I tried it 4 times...I will keep trying...everytime I try...I can make it ...
