I dreamt the Milky Way was a river you could wade into

I'm standing on the bank of a slow, glowing current — the water is made of stars, and they drift past like pebbles, some of them singing. I step in and it's warm, and I can see constellations moving under the surface the way fish do. The whole time I know I'm dreaming, but I don't want to wake up because the sky is missing back home.
