What does vk do with daydreams/fantasies?

Sometimes our minds wander into fantasies. Say I'm reading a book or watching a movie and I have vk on. For a while I might escape into empethizing with the characters and feel their pain pleasure fear or whatever. What about little kids who dream up all sorts of silly things like living in a castle made of chocolate icecream. Sometimes its fun to daydream, but deep down inside you don't really want those things to actually happen. I kind of think vk just cosmically laughs at those and moves right along but I'm curious to know what the teachers have to say. Thanks
