This is the very old (i belive Slovan) legend.art was inspired by Kazik Staszewski's song "poludnica" - (means : "highnoon-er" ?or something like that).

What should You do if you meet Poludnica.Well, it is probably too late for any reaction cause you 're already dead.But at least You can do this: "When You realize ,that is a girl you've just met in the middle of barley field at highnoon, is acctually Poludnica- don't run! It may turn her very angry and if there is something worst in Poland than Poludnica - it is definitely Poludnica which has been pissed off " good luck
