Said entity/entities may have seen your hobbies and thought, 'Mmm, a kindred spirit, wanna have an experience together?' I have encountered things that got physical before, but they listened when I said no. One tried tickling me as if saying, 'Notice me,' but stopped when I said I needed sleep. I am pleased to hear your situation has improved.

now that is an interesting idea. local spirit. and it would match the previous experience of having 'something' hang out for a while. however, before doing the banishing that actually worked I yelled stop quite a bit. granted, I was yelling at my unconscious mind, because Im trying to stay as rational about it as possible.

pic related. Im probably fucking nuts. the odds of this not being a new trauma or mental illness symptom seem pretty low... just really weird that the occult guy in me could make it go away and the atheist guy in me that tries to be as rational as possible is still wondering what the trick is, because there has to be a trick. theres a mushroom that causes women to do this when they smell it. that means there are sense receptors that can unconsciously trigger this behavior. or I could have a lesion on some sex part of my brain.

If you wish to explore the medical side of things, you could request to have tests done to see if any conditions you have or things you have been exposed to have influenced your conscious and subconscious. 

Bacteria in the intestines can also influence brain activity. A paraplegic experienced orgasms when sucking his thumb after his brain adapted to the damage his lower body experienced, and the visual cortex has been said to adapt to audio for blind people in the UK who experimented with acoustic spacial awareness. There could very well be some neurons which have crossed in unexpected ways, but further studies and testing will be needed to confirm it. You can ask a university if they would be interested in doing an analysis with presenting your records as clues for what is occurring.

There are many aspects of life we have yet to discover, both in the seen and unseen, and all we can do is our best.
