The purpose of this thread is pretty simple: ask people if you’re remembering something that’s actually from a book, or if you dreamed it. Maybe someone will know the book it came from, if such a book exists.
These are mine, feel free to add your own as well as weigh in on mine if they ring any bells.
Is this from a book or a dream? A plant, which grows in an alien landscape or fantasy setting, looks startling like something that has been strangled to death. The plant might look like a strangled person, or perhaps a kitten(?)
How about this? An exterminator sets traps expecting that his client has a rat problem, but when he checks the traps he’s caught something else entirely: little rat-sized monsters.
