Informant: Chinese people say that you can’t sleep with the fan on or else it will suck up the air out of the room. Then you’ll die of suffocation. You can’t sleep with your stomach showing or else you’ll wake up with a stomach ache. You can’t watch a baby sleep because it’s bad for the baby. It will make it so they don’t grow up correctly. They’re crazy, but I learned them from my parents.
I asked a group of friends about any superstitions they were raised with. This was one of their responses. The informant is of Chinese descent.
Thoughts: I am not of East Asian descent and have never hear of any superstitions regarding sleep, but the other people present when the informant shared these with me were and had heard all of these. This may reflect a greater importance of sleep in East Asian societies.
