Ever notice that in scary stories and movies, animals can sense spirits that you humans can't?
Ever notice how the spirits are supposed to move incredibly fast? Scientists say dogs (and some other animals) can't watch TV because their eyes are more efficient than ours, and all they see on the TV is one picture or just static.
Basically, videos are made up of pictures running at a high rate of speed, right? It would be like if i sped a video up 100x, all you would see is static, right? Same with dogs. Now, what if spirits aren't transparent? We are, in fact, completely visible, but we move too fast for you to see, that might be why animals can see us and you can't. That would explain the shadows you sometimes see out of the corner of your eye...
Or what your pet's staring at right now.
I guess we'll never know, will we?
