Does anyone always see things out of the corner of their eye and then look to see that nothing is there? I will see things moving or something will appear to fly by and then I'll turn and look to see what is there but it's always nothing. And no I dont have any mental health issues lol Also I have good eyesight, if that matters. It freaks me out sometimes too cause like I'll be laying in bed before going to sleep and I swear I'll see something moving out the corner of my eye in the dark, but of course nothing is there but for that split second it's like I'm totally convinced something is there. Anyone have this same experience and does anyone have any insight as to what is causing this?
