What i saw during the eye migraine when closing my eyes was jittery jagged short bright lines, together forming a half moon. When i looked that up on the internet back then, it was explained as symptoms of 'eye migraine' and i believe it is an inflammation of the visual nerve. The disappearing numbers on the clock were quite scary, that is why i remember.
