peripheral vision is sorta...freaky for me sometimes.

Like, when I'm sitting here on the computer, and there's a white shoe on the ground next to me, i'd see it in the corner of my eye and I'd SWEAR that it was my white cat Buffy.
When I turn my head, I realize that it's just a shoe...

Things like this happen to me CONSTANTLY, and it really bugs me, a lot.
Especcially this tiny stool that sits under a tree that I always see on my way home from school.
As I stare forward, listening to my ipod, in the right side of my eye I swear I see a cat.
EVERY. SINGLE. TIME.
It's so crazy! I can't tell you how many times my brain portrayed the stool to be a cat, even though it's been there for YEARS.

It's even worse at night when it's totally dark, and when I enter my room before I turn on the lamp, sometimes a shirt hanging on a hanger will REALLY look like a human when I'm not staring directly at it, and I'll totaly freak out.
Like once I went downstairs late at night to get something to eat, and on the banister I hung my sweater out because I was lazy and didn't put it on the coat hanger. Naturally, I barely see it and jump. EVEN THOUGH I was the one who put it there not an hour ago!


So, is it just me - or does anyone else have issues with their peripheral vision?

BTW- I know it's not REALLY a "paranormal" topic, but I do know that it's NOT normal.
