The idea
Consciousness is awareness of internal and external stimuli, and it varies continuously in level across a day.
In practice
Alert reading, drowsy listening, and dreamless sleep are three levels of consciousness in the same person.
Where people slip
Consciousness is not a switch with two settings. Most states of interest sit between full alertness and none.
