A manifestation of your own mind
Your brain is a drunk man who took a karate class and forgot how to walk
You told your friend your brain was a drunk man. They said, 'That’s why you trip over your own feet.'
You said your teacher looked like a drunk man who forgot how to walk. She said, 'That’s why I give you failing grades.'
You told your dog your brain was a drunk man who took a karate class. Your dog barked at you like you were a problem.
