I did a weird possession, and I don’t feel so comfortable talking about many of the details, but I will say that is was a “higher self”. They felt like they were the person. I tried automatic writing and it was weird. Some of it I accidentally messed up. But here were some mannerisms they portrayed:
Swiveling my head around a lot to look at things I would personally deem uninteresting
Staring at me/my body in the mirror for long amounts of time
moving about the house and just fiddling with things.
They said some illuminating but scary-to-accept stuff. I am not sure if it was true. Does this sound like a possession to you?
