Dream of

I was teaching at a school as a student teacher and suddenly one of the teachers stopped me and was like "why do you have a tattoo" and I said, "I don't" and then I looked at my left arm and I got this cold shiver feeling all the way up my arm and as I did a tattoo of letters and numbers and Roman numerals appeared eventually it went all the way up my arm to my shoulder and when we wanted to show the nurse it slowly started disappearing and then the nurse said something about it having to do with smoking but I only smoke weed and somehow my dad was involved... it was weird
