Mediums?
From Create Your Own Story
"Mediums come in several different flavors. VERY few people are spirit mediums, and those that are generally fall into one of the following categories:
"Channeling the dead's bodies. These mediums can take on the physical form of any departed human, including their voice. However, they cannot communicate with the spirit itself. "Channeling the dead's souls. These mediums can communicate directly with spirits in the other world, in the same kind of environment that we're in. While in the spirit world, time stops completely. "Channeling the bodies or soul of a sleeping or unconscious person. Useful for communicating with someone who is far away or comatose."
"Are there a lot of mediums in the world?" The odds of being one of those four kinds is about one in 100,000, however there have been people known to have more than one of the abilities. The record, I believe, is three. Do you need to know more, or have I already talked to you about espers?"
