There is a game called hide-and-seek whereby you close your eyes, turn 10 rounds (while you are turning, the other players go into hiding). Upon the 10th turn, you open your eyes and start to ‘hunt’ for the players.
What is in your mind when you are turning? Most likely it is blank. The dizziness sent you into trance state. Your logical mind cannot think and you enter into a subconscious mode.
When the subconscious takes control, you are said to be in hypnosis.
