Most people think that hypnosis must be conducted when a person is lying on a recliner or bed. Or at least, be seated comfortably on a chair. This is a limited understanding.
A person can simply enter into a trance state when standing.
Have you ever stand in front of a bush of flowers and see the butterfly hanging around them? You marvel at nature at that point of time, and your mind is not filled with other thoughts.
Or have you stand in the bus or train and half-sleeping? Your mind is drowsy and you don’t really think of anything else.
These are instances of standing hypnosis.
