Not So Serious
Our daytime consciousness is a bit of a clown.
After several hours of oblivion, we wake up in the morning and find ourselves in a state of survival consciousness. Our mind, emotions, desires, and sensations are all geared to ensure, as far as possible, that we continue to persist as best we can. This survival consciousness is a bit of a joke, being a product of the brain, and has the sole function of supporting our efforts to get the resources the body needs. Rats have a less sophisticated survival consciousness, but it does pretty much the same thing.
