What is the origin of the bubble during sleep trope?

Question

A common trope across various anime and manga is the snot bubble trope. I've put an example below:

I can gather what it signifies from the TV Tropes description, but what's the origin of this? Does anybody know where it was first used, or where the inspiration came from?

Could it come from little babies who have running noses all the time and when they fall asleep after a tiring day of running around it might create snot bubbles... — Peter Raeves, May 27 '15 at 19:38

The origin is, perhaps surprisingly, real life! This does occur among children in Japan and in other countries as well.
