Something's Missing

But is this really where I'm meant to be?
Blue silence, but music in my chest.
Feet on the sand, and my mind's a mess.
Too many voices, none feel real.
I'm in the moment, but I don't feel.
I breathe in, but can't define.
I close my eyes, let it all flow.
Maybe I don't need to know.
Maybe I don't need to know.
