Bathroom Monologue: Astral Plane or Astral Plain?

It's kind of both. It's a plane of existence if it’s anything, but there are also rolling hills. The souls of buffalo roam, and long-extinct races of antelope play. They do not, however, play harps. It’s lovely at night as instead of daisies, stars bloom in the grass of these fields, and twinkle a far sweeter music than man has ever known. He has felt it in a fashion, though, and expressed it by accident in every song that bring to mind places without using words.
