I've gotten that feeling from dreams sometimes -- not forgetting the content or having it be something illogical, but instead being a very concrete and visceral situation or concept that is impossible to put into words or even into conscious understanding. But it's usually a "just woke up from deep sleep" feeling -- wild to think about experiencing that with a waking idea.
