I have met one single entity in my experience, and it was the metaphysical manifestation of the unfavorable conditions I impulsively decided to smoalk in: frigid bedsheets, total darkness, and lots of unwanted background noise. It took the form of a pair of dentures with two big floating eyeballs, and it pulled me through a claustrophobic labyrinth of red and white rooms. The whole time I was trying to ground myself by feeling the only part of my body which had any sensation—the inside of my mouth (hence tooth demon?).
It enjoyed mocking me for being such a fool. That experience was more funny than scary, though. I had a good chuckle even right after. Never doing it that way again, though.
