I have not been to the otherworld yet-  but I am researching in preparation for my first trance entrance

"Shamans live with one foot in the mundane world, and one in the world of spirits. This parallel realm is called non-ordinary reality.

One of the most interesting things about it is the fact that it comprises three main parts — and, no matter where you go or whom you speak to about it, the experiences of shamans within this non-ordinary reality are consistent the world over.

The three worlds within non-ordinary reality are broadly known as the lower, middle, and upper worlds. Each has their own characteristics, inhabitants, and purpose."
