People with autism sometimes do weird or different movements with their bodies. This is weird to most people, but not to autistics like me. Sometimes our brains make us do moves that we can’t help or stop. Understand that it’s utterly not bad behavior, it’s how we process lots of information.
I like to illuminate my mind doing drastic moves like jumping and rocking. Sometimes I use my feet to bang on the floor, and get my mind on track again. Movement like this helps me align my mind to pleasing aptitudes of autism calm totally awesome.
So if you see someone with autism doing drastic moves, don’t be alarmed; they are just helping themselves.
