Hallucinations are certainly not by definition destructive. If you play Guitar Hero for a few hours and then look at something stationary, it will look like it's moving. If I haven't gotten enough sleep for several days running, sometimes walls will look like they're at the wrong angles.

Tetris effect/hypnagogia is maybe what you're talking about, it happens to most everyone given the circumstances http://en.wikipedia.org/wiki/Hypnagogia

Guitar hero purposefully bends the score screen so that when you look away, your brain maps the bending & shifting of whatever you're looking at. Similar to those optical illusions "look at the X colored dot for 60 seconds then look away"
