I was working on a system that was doing CSG of AI nav meshes. If enough floating point error crept in, eventually the a shared of edge of a navmesh would split apart and you'd be left with the AI walking around non-existent obstructions. Spent an unimaginable amount of time trying to deal with this. One night when I was walking back to my apartment, I walked over a section of the sidewalk that had plywood laying on it. The edges of two pieces of plywood had about an inch gap between them, and I remember my heart jumping in panic as though I was "seeing the bug" again - basically hallucinated my work problem into real life. That was towards the end of working in the game industry...

When I walked out into the night, I perceived RL trees as the software would render them. I wonder how much of this overlap goes on without us even realizing it :)
