A normal state of mind, you just don't notice it usually. People go in trance all the time. Have you ever driven a car on a highway, at night? Do you remember the lights, the sound of the car on the road, how you felt the vibrations of the road through the steering wheel ... As you think about this experience, I don't know if you agree that this is indeed a natural trance, but if anything happened, you would be able to react quickly anyway ...
