Question

Are there any well formed definitions of "trance"?

Answer 1

"The necessary and sufficient condition for a trance to occur is whenever there is a sustained cognitive object loop of sufficient length of time to cause dissociation. A cognitive object is an abstract way to denote a thought, any thought, whether it is a word, and idea, a feeling, a vision. When a set of cognitive objects repeat often enough, you will go into a trance."
