Soul dualism

Finally found the word for it!

https://en.m.wikipedia.org/wiki/Soul_dualism

Soul dualism or multiple souls is a range of beliefs that a person has two or more kinds of souls. In many cases, one of the souls is associated with body functions ("body soul") and the other one can leave the body ("free soul" or "wandering soul"). Sometimes the plethora of soul types can be even more complex. Sometimes, a shaman's "free soul" may be held to be able to undertake a spirit journey.
