What if possession doesn’t start with a demon in the room, but with a thought inside your head that no longer feels like yours? This episode dives into intrusive thoughts, thought insertion, voices, delusion, and the fragile machinery that lets us call a mind our own. Then we descend into the strange case of Daniel Paul Schreber, whose visions of divine rays, nerves, God, and control became one of the most infamous accounts in psychiatric history. No spinning heads. No movie theatrics. Just the quieter horror of a mind learning not to trust itself.
