This reminds me a lot of an experience i had on shrooms and MDMA.
I was skating at the skate park and ended up in a confrontation... a blade was pulled on me... and, well...
Needless to say, I'm a violent person. Give me a 24 inch crescent wrench and I can do a lot of damage, especially when I have no clue what the fuck is going on, and i'm fearing for my life.
From that experience I've learned that psychedelics are not to be used in situations where confrontation is a possibility.
