Taking this to the logical extreme are things that can only be experienced. E.g. I can read about oysters, but I will never be able to understand what an oyster tastes like until I eat one... until I experience it.

When communicating, the more the topic involves an experience the harder it is to communicate. We use metaphor, simile, and analogies to help people relate it to something with which they are familiar, but it fails for many reasons. When building a prototype for a new camera system, we began with a physical mock up which was cut from wood and painted. The client's first comment was that is was garbage because no one would take a wooden camera seriously. Even after an hour-long presentation, his final comment was "This all sounds great, but it absolutely cannot be made out of wood." Some people have terribly abstraction skills, and there's simply no getting through to them until they see the final product. They need the experience to understand.
