No, i never had that, or saw someone who had that.
But interesting that you start about this, because a couple of years ago, we were tripping on shrooms with some friends (thai and mexican shrooms, i think), and suddenly something really weird happend.
One of my friends was getting a purple/red/blue spot next to his nose and under his eye. And it started to grow, and within a couple of seconds it looked like he was punched in his face
He wasn't punched in his face, because we were just tripping outside in the garden and smoking some weed
Also his eye started to close.
A few minutes after that, it was going away, and you only saw a little blue/purple spot.
Everybody saw it (also the people who didn't ate shrooms) and we also have a picture of it, so it isn't a hallucination. It was real.
We didn't and don't know what caused this, but maybe a allergic reaction?
Very strange, because that dude wasn't allergic for shrooms or that spicy.
It wasn't his first time doing shrooms.
Maybe shrooms can sometimes cause allergic reactions to some people?
