shallow sea

I want to go to a shallow sea, a shallow sea that I don't know where it is. Is it a specific place?　I think there are two possible meanings of "specific": one is a place that exists and can be reached by some means, such as the coast of somewhere. The other is a place that exists and can be reached by any means, although it is not specified as the coast of anywhere. On the other hand, there are also abstract, conceptual, imaginary, shallow seas that do not actually exist. They may exist somewhere else, not just in our minds. But it's just an image, it doesn't really exist. I can't go there. I would like to say that the shallow sea I want to visit is such a shallow sea that does not distinguish between the latter, which is concrete, and the abstract, which I just mentioned. There is another way to think about the abstract shallow sea, and that is that the shallow sea does not actually refer to the shallow sea, but to a sign that may not even be a sea, or even a place, but only a sign that refers to a thing of a completely different dimension. The meaning of the expression "I want to go to the shallow sea" may not be that I want to go to the shallow sea. But as I said before, I want to go to such a shallow sea, where both the latter of the concrete and the former of the abstract are mixed together.
