I have an odd problem. I live in college and hense am quite a big drinker (I know i know - i am an idiot!). I have noticed that the night after a big night out, when i am quite tired and trying to sleep, that when i close my eyes i experience a sensation where the blackness seems to become 3D (or attains a certain 'depth'). I see people's faces flash in and out of my vision. Other times i get heavy blotching like when you press on your eyes for too long. I have found that these sort of visions are not necessarily related to drinking as i experience them if i have a few very late nights in a row due to studying.
Does anyone know what this could be? Could there any possible links to stress and dehydration of the brain?
Thanks very much!
