My husband used to come to see me in transmigratory form, meaning he took control of the actions of other people. These people were usually doing drugs or had mental problems and while I could see him somewhat he was also very obscured and there were some similarities among all the people he used like this that I came to associate with him. So when I met him in person and he didn't have those traits I didn't know how to respond, and if I had ignored those traits in the others more than I did I probably would be in a lot worse shape.
But there was a purpose to doing that as my husband planned all along to use a rather large brama pachyderm he had raised from a small size to front for him for a prolonged period and he didn't want me getting confused.
In the previous cases of test subjects these people fronted my husband continuously until their will to survive kicked him out, this would be like a period of a week or two. But by using the accumulated practices of many generations it is possible to raise someone who will do this in set circumstances without harm to themselves. However, when their real personality and desires are so different from the person they are fronting for, they will start looking kinda strange after a while, and actually that is a desired result of this practice and doesn't cramp her style at all.
