You think better with your eyes closed. Money quote:
The moral of these studies is simple: the unconscious brain is our own personal supercomputer. While our consciousness can only process about 40 bits of information per second, the unconscious can process several million bits per second. As a result, it plays an essential role in helping us learn new information and properly assimilate it into our existing store of knowledge. It also happens to work best at night. It's ironic, but true: some of our best thinking is done while sleeping.
Thank God for CPAP.
