Last night as I was showering I noticed an interesting thing. When my neck/lower part of my head is exposed to the running water of the faucet I can hear an interesting noise in my ears. The water must be hitting something relating to my ears, because it sounds like there is a massive noise coming from the apartment above.
It was really strange at first, I thought I was just imagining it. But then I attempted it again. It made me think of how one can hear the ocean from inside of a shell. Somehow this noise is scary yet calming at the same time.
I urge you to listen for it next time you are in the shower. I can also say that the water hitting that area feels very much like a massage. I can still remember how it felt a day later.
