The Theta frequency band (Hz 3-7) is a brainwave produced between waking and sleeping. When our left brain is in the theta wave state, the left brain will be “closed”, and the right brain will be “activated” to become active, clouding in consciousness, but the creative inspiration is endless. Theta is a state the artists and writers often pursue for, and people can reach this state under the effect of drugs. Of course, we can also reach this state naturally when we are meditating and deeply relaxed.
