"...sometimes you can't tell earth/lake from sky (there are reflections of stars on the lake) so it feels like you are floating in space."

I saw a night like that once in mid-Pacific when I was in the Navy, the water so still and the sky so clear that it was difficult to tell where the dividing line of the horizon was. The ship was dark except for the running lights required by maritime law, and by choosing the right spot in shadow on deck, their glow was invisible. And streaming behind the ship, in a straight line to the edge of the world, was our bluish-green phosphorescent wake, a highway in the sea, or perhaps the exhaust of a starship, micro-organisms in the water stirred up by the ship's screws.
