Liberals and Sleep

The so-called "liberal (actually leftist) world is a tough one. The latest study. shows the following about liberal vs. conservative sleep patterns:

Among his findings, Kelly Bulkeley discovered that liberals are more restless sleepers and have a higher number of bizarre, surreal dreams -- including fantasy settings and a wide variety of sexual encounters. Conservatives' dreams were, on average, far more mundane and focused on realistic people, situations and settings.

Gosh. It has always seemed to me that liberals were lucky. They don't even need to be asleep to have "bizarre, surreal dreams." They merely need to be talking politics.
