Is there a book about characters from horror movies going to therapy?

I'm looking for a book my sister wants to read.
I thought I heard of one somewhere, (a book about horror movie characters going to therapy) I told my sister about it. She wanted to read it, but when I went to search for it I couldn't find anything.
I'm just wondering if there is a book about that or if I'm wrong. And if there is a book. What is it called?

Sorry to waste your time, this is probably a stupid question..

the only thing i can think of is that one webtoon called melvina's therapy
not sure if that's what you're looking for though
