Inhabited by beings. It's a concept I learned about in some of our "psychic" work.
Is that a thing? Yes, I believe so. You are a human being. You have some kind of physical integrity, you have a body, a mind, you have habits, and routines. You think and say stuff. You walk around in the world.
You don't know it, but you can be infested with other beings. You are the host, and invaders enter, and inhabit you. And take over the control panel. And once other beings take control, all your habits and routines are subject to change. How you look, how you think, how you act in the world, suddenly morph.
How do these other beings do it? Sometimes it happens in a blink of the eye. A word, a thought, can open the door.
Or it can be food or drink. Or alcohol, drugs. You can't see yourself, when you are inhabited. You don't know! You are blind to the infestation. Your body, your mind, is held captive by other forces.
I have witnessed this phenomenon. It's a sad and scary thing to witness. You are helpless. You can't do anything except sort of guide the victim to a safe environment. Try your best to get them somewhere where they won't hurt themselves or others.
It's kind of like a voodoo thing. Do I believe in voodoo? Yes, I'm sorry to say, I do... the voodoo comes from anything that can enter a being... and a being can be entered!
