Daydream and Hypnosis

Hypnosis is an altered state of consciousness.

We drift in and out of beta consciousness (conscious state) and alpha consciousness (surface of unconsciousness), especially so when we are tired. When we are highly energized, chances of remaining at beta consciousness for a long time is very high.

Daydreaming occurs when we are engaging too much in our left brain activities, such as calculation, language etc. The right brain is being ignored and no activities or not much activities are being engaged eg music, arts etc. Under such circumstances, our brain (more specifically the right brain) becomes tired and drift into the apha state so much so causing us to become relaxed and idle. This is when we start to daydream - it could be a dream of reality (like going for a tour) or something of fantasy (like flying on the moon).

Daydreaming is thus a form of hypnosis.
