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"
Hallucinations are psychiatric states, characterized by confusion, loss of identity and control, and have a destructive nature.
Visions on the other hand are spiritual experiences, they come with clarity, finding of identity and control about the inner and outer world, and are very constructive and uplifting experiences.
