Glad to know I'm not the only one who sees these "things". Although with me it's been diagnosed as a mild psychosis or a very mild psychotic event (a slight hallucination) brought on by stress or being put on the wrong medications for years.
Maybe mention it to your doctor in the event is is a detaching of your retina or a symptom of metal illness. Either way you're not the only one who sees shadows or as I refer to them as "bugs" moving just out of sight. Also, lay off the Creepy Pasta, that stuff messes with your head regardless of your mental state.
