I would appreciate some assistance in learning about a particular topic.
If my interpretation is correct demons from The Bible and symbiotes from Marvel and vampires from Buffy/other IPs are all just different ways of talking about the same thing.
Could you please comment with or link to any relevant information you have on possession/symbiosis?
Also, if you have been under general anesthesia.
A lot of people get possessed in hospitals.
It's as if certain substances leave the front door wide open so anyone can walk in and take up residence.
