Juan Pestañas. I'll let you all guess at what this one means.

In the UK and Northern Europe the Sandman sprinkles dust or sand on children's eyes to help them sleep and have sweet dreams. I assume Mexican children are visited by Juan. Scary?
Here, the Sandman is a good thing. We also have the Boogeyman who comes if you're bad.
Now looking him up on Google, he seems to be more like Mr. Rogers here in the states.
From the gist of this video, I get that Juan Pestañas comes is giver of sleep in Mexico. I can't think of what or who we call it in English.
Bogeyman (Boogeyman ) could be corruption of "Bony" which was the nickname
of Napoleon Bonaparte , he was used to frighten children in the 1800s.
It could also have come from the Bahasa Malasia -"Bugis man" -"pirates".
