Informant is an immigrant from Korea. First moved to Paraguay around his teens then to Los Angeles in his 20s.
Superstition as told by informant: One thing we believe in is not sleeping with the fan on. You always liked doing this which annoyed me, but I’m not that superstitious so I just let it go.
Upon further research I couldn’t find anything on why having a fan on when you’re asleep is associated with death, but I did find out that if you have a door or a window open while the fan is one then you should be fine. It is only in closed rooms that this superstition applies to.
