I was always scptical about these things but then one day I met a fella that claimed to be a phsycic.
This was at a social gathering and I of course asked him all about it.

While he was talking to me I had the most peculiar and unnerving, crawling, tingling sensation from head to foot along with a sudden intense knot in my stomach like you get on a rollercoaster or something.

When he moved away to talk to someone else the feeling dissapeared instantly.
I mentioned it to him afterwards and he said that I was feeling the presence of the spirits he could see around me.

I personally think he hypnotized me or summat.
