I have for some time, that sometimes I want when I lie at night and sleep in the bed, so did light flashes before the eyes. So, it is completely dark with me and I can rule out that there is actually light. It is then as if I light up with closed eyes someone a flashlight in the face and then quickly turn to the side. Just as if it is just light and then is gone. I did about once a week, if then more times consecutively so ca 20 times in one night with breaks of a few seconds to minutes. It has become a bit more often lately so I wonder if it may indicate eye problems? I have the eye but really just closed.
