Black Blur

I've been seeing alot of black blurs out of my peripheral vision recently for some reason.

It's been at random places really, nothing consistent at all. Once I was sitting in my car waiting for someone at night and I see it to my right but when I turned to face it, I saw nothing.

Few other times I've seen it during the day just in malls or at home.

It's just this... black thing, it kinda moves around on the spot for a while and when you look at it, it disappears.

Yes, I figured it could be like a bush moving in the wind or something but there's usually nothing there when I look... so hard to say really.

I remember reading about this a while back and a common theory is that of "Shadow People".

Some sort of paranormal activity where these 'entities' appear and disappear as quickly as they come. I think back in the olden days they were thought to be demons that fed off fear and lived in the darkness.

Creepy.

I think I'm just tired but just writing about this is kinda giving me shivers down my spine.

Maybe I'm going crazy.

I think thats more plausible and probably even a better option.

No, I'm tired.
