Kinda creepy

So I keep having this recurring image/thought in my head of me a work and getting my arm stuck or cut off in the 60qt mixer. I have this thought like 2-3 times a day on average and it totally creeps me out. Back when I was just starting out there I got my wrist pinched under the hook when it rocked back as I reached in, but I don't know why I'm having these thoughts about getting caught in the mixer now.
