A shell-shaped building / 貝の形をした建物

I went inside of a big shell-shaped building. It was a place called museum. Museum is a bit like the ocean. Seems like less gravity here. Things float, so as the minds. I listened, quietly. Even the heaviest soul here sounds serene. Museum must be a place for meditation. A security guard came to me to tell not to take photos. But he smiled instead when he realized I was just listening to human minds.
