This looks very Photoshopped. I'm hoping this is an XKCD moment of erroneously mistaking life for fakery.

I have had something like this as long as I can remember. About two weeks. [rimshot]. Seriously though, my experience is nowhere near as bizarre as the writer's, but my personal spatial anomaly has the added feature of controllability. I can choose to make it stop, and, occasionally, choose to make it begin.

The "hallucinations" for me are limited to scale only, never warping. When the effect is happening the world has no scale. Objects are simultaneously as tiny as a grain of salt and as large as a planet and also simultaneously within arm's reach and miles away. Or maybe it's me that has an ambiguous scale. Either way it's even freakin' awesomer than it sounds. It can happen anywhere anytime but for some reason it ALWAYS occurs in doctor's/dentist's waiting rooms.
