dementia

When you are sick of either three-dimensional or two-dimensional media, so you want to see something different.

Whenever I get dementia, I switch from Super Mario Bros. to Super Mario 64, and when I get sick of both, I crave a fourth-dimensional Mario game, so now I'll have dementia until Nintendo makes that.
