What do you think about psychological fictionkin? What about people who are a mix of both spiritual and psychological?

Psychological fictionkin are completely legitimate, and I definitely understand that its hard to believe in concepts like souls and alternate dimensions that aren’t proven. I personally believe that those of us are truly fictionkin are all experiencing the same phenomenon, but I have no idea what the explanation for that phenomenon may be. Maybe its spiritual, maybe its psychological, maybe its somehow a mix.
