Do you think your creations (fictional worlds, species, characters, etc) ever "come to life" outside of your imagination? In other words, do you think they ever enter the dreams of people, influence art, influence real people's personalities or actions, etc?

I was thinking about my fictional characters the other day, and I got to wondering if they ever actually come to life in any way. Do they exist beyond just my imagination? Do they exist anywhere at all?<br><br>I've thought about it a lot since, and I don't think they do. But I thought it would be interesting to see what you all think. Do you believe that they exist?
