What does trance feel like?
The best thing that it can be compared to is the state an exhausted person is in shortly before they fall asleep, where they are still awake and actively aware of their surroundings but their mind is wandering and creating images and dreams seem to be flooding in, except that one is wide awake, and the mind seems more focused. Beyond that, it can only be said that it must be experienced in order for it to be explained because it is not completely like anything else.
