Hmmmmm, well i know that it is possible to have your guide fuse your souls together. I have done this with my guide. And what we do is think our souls merging. But i have to think about part of myself being locked away. We are literally sharing my body while our souls are merged together. It is a really personal experience. But to all those who would call me fluffy I am NOT talking about spirit fusion like dragonball z. It is different.
