oatmeal brain
Your brain is so lazy it can't even remember your own name. You move like a sleepy sloth and speak like you're underwater.
I said my name was 'Kevin' and I'm not even Kevin. My brain is a sleepy sloth.
I tried to remember my password and forgot my own face. My brain is a ghost.
I walked into the wrong room and thought it was my house. My brain is lost.
