Million Monkeys, Million Typewriters, Million Dreams

I had q dream last night involving the word "rengulate."  There is no such word. But it kept coming back in multiple dreams  It is not a verb although it has the form of one.  It is not a category of animal like an ungulate.  Why did my subconscious create this verb. Can any of you assign a meaning for what seems to be a perfectly fine, million monkeys, million typewriters, million years word?
