This is weird, and no I am not schizoprenic or otherwise have any mental issues (as far as I can tell, anyway) aside from depression. I keep seeing a faint after-image sort of thing when i look at bright enough surfaces. The image is, of all things, a FreeCell card game, and it seems to be consitently the same. If I study it long enough I can actually make out the values of the cards. I do play FreeCell a lot so at first I thought this was some sort of retinal afterimage (if that's even a thing) but its been happening for over a day now and it keeps showing up - it just seems to be constantly there. It is very faint and barely noticable most of the time, but it is definitely there. What is this? And yeah, I said I'm not schizoprenic but this is starting to seriously make me doubt my sanity.

No idea if this is relevant, but I did recently increase my dosage of escitalopram and I also regularly take acamprosate (I'm an alcoholic), propranolol and OTC allergy meds, although I have been taking all of these for a while without any noticable side effects.

I'm a 44 year old white male, 6'4" and 220 pounds and I vape. Also, I wear glasses (and no, the FreeCell cards are not attached to my glasses)
