I have a DVD balanced on my phone about 14 inches away from my head sitting on the table on a small stack of magazines. I don't know why, but I glanced over at it. Here's where it gets weird. I had to KEEP staring at it because I could swear it was tilting down and slipping off of my phone. It wouldn't have meant anything other than my phone being slippery but I couldn't fathom how after a half-hour, suddenly the DVD would start slipping now. But the longer it took to fall, the more I considered: is this real? I had to take into account the edge of the DVD in comparison to the edge of the magazine beneath it. It had never moved at all! My eyes were being tricky due to a change in focus.

Aside from my mother having a case of vertigo, I've also encountered multiple moments of seeing something move that hadn't moved.

Anyone else experience something of the like?
