Hello! I'm creator of list of Slavic mythical creatures page. Kinda late answer, but:

You asked about what creature Hym from Witcher 3 is based upon. I don't know the creature that matches Hym's behavior, but the closest one I can think of is Mora - demon that causes sleep paralysis and nightmares. Either that, or Besomar - demon that drives people into hatred and insanity.

Besides the fact that Witcher is heavily based on Slavic mythology, it also borrows some of creatures from its neighbors. Perhaps there is a creature from another mythology that matches Hym's behavior.

Cheers :)
