My BM smelling like a patients BM

Title is very weird and gross but we are all used to it and don’t know how to share with the world but here, do you guys ever get a whiff of your own bm when going to the bathroom and then boom it smells like one of your patients stinky blow out you cleaned earlier in the day? I don’t know if I’m loosing my shit (no pun intended) but it really throws me off because I know the smell of me and that is not me in the toilet if you get what I’m saying.
