The only one of these I ever heard of was a version of the drowning ghost. But only one river and it was a guy who jumped after losing his girlfriend to a flood. He would grab any girl who swam by thinking that it was her and he was trying to save her. (How they knew the ghost's motive I am not sure but that was the story)
My grandma on the other hand (not Hispanic) did tell me the one about the ears burning.

- don’t take an unbaptized baby into a cemetery
- don’t bring a baby or toddler near a pregnant woman or they’ll throw tantrums.
