Dreaming in little diamonds.

Its normal for someone whos playing a lot of a new video game to have dreams that are influenced by the game. So had I started having Civ III dreams I wouldn't be surprised. However, I remember my dreams from the last few days and though they were interesting (at one point I was a split personalitity private detective/secret agent, and the detective self was hunting the other half as a suspect in a political assassination...), but they did not involve Civ 3.

Why then, did I wake up both mornings with my eyes attemtping to make all objects fit on a diamond grid, and with a tendency to refer to myself as 'that unit'? In both cases I found myself getting a drink of water and thinking 'That unit is thirsty, better let it drink.", a way of thinking about myself that I found somewhat unnerving.
