I am playing chess against Someone Else.
The game begins. At first, it is a perfectly ordinary game of chess. As it progresses, however, small blue dots appear in the center of squares that a piece I am considering moving could potentially move to.

The game progresses. I come to rely on the little blue dots, and use them to play positional chess. I make to move my queen -
and the little blue dots break.

Suddenly, I can't move. I can't consider any moves other than the queen, and blue dots are drawn in most of the squares, completely regardless of whether or not the queen can move there. reality developed a severe memory leak.

A few seconds after everything locked up, I awakened, feeling a bit uneasy. dreams are supposed to be stable.
