This is a very strange you tube video about new age stuff,
but this girl blinks and you can see her eyes through her eyelids all
the way through the video.

I think you are seeing a shape shift of some kind or a hologram.

THIS ONE IS WITH HER EYES CLOSED WHILE SHE IS BLINKING.
ITS REALLY WEIRD!

Its due to the bad quality of the video. She doesn't have transparent eyelids, just a crappy camera.

That's what I thought, but how does that happen?

That's really funny but I have also seen that happen while using a video camera. You can see right through some things.

When you blink, your eyelids move too fast for a cheap camera (or one that is set up wrong) to capture. What you end up seeing is, in effect, something like a double exposure, where it appears as though you can see one item through the other.
I'm not an expert, but I beleive this has something to do with the speed that the camera records at. The fewer framers per second, the more likely something like this would happen.

Do you think so? While your explanation makes perfect sense and was something I hadn't even thought of, I did notice, at least in the older video cameras, that even if a person was standing still I could see right through them when filming sometimes. I don't think the camera captured that, but I could literally see through them myself.

I thought it had something to do with the strange ways the lenses were alligned -- either that or it's a revelation that none of us want to admit: As some have suggested, we really "may" not exist and may be holographic after all!
