Koreans believe fans to be dangerous to use while sleeping

tbf i believe that too and i’m not korean. the reason i believe this is because of my real-life experiences. When AC is running, it typically gives me the sensation that the air it gives off is not just cold, but creepy cold, like an iron rod is not just hard, but hard enough to smash somebody’s skull with it. The same intensity is the coldness from the typical ACs that i’ve experienced. At least some of them.
