There is a memetic, self-replicating animal. A person affected by it will hear its call very often, and become paranoid. When they try to inform someone of it, since there is no actual animal to see, they attempt to reproduce its call. Any person who hears an impression of its call will become affected by the meme, but the noise they will hear is identical to the impression that they heard. That way, like a game of telephone, each person affected by it will have a somewhat different noise that they hear.
Is this a good idea at all?
