I live in southern Australia,latitude 36 degrees south, once in every few decades we will be able to see the aurora australis (southern lights), the last time it was visible was about ten years ago (that I know of), I had a housemate at the time who came home late one night and saw the aurora. He told me in the morning, he thought about waking me up but decided not to.
I would have killed to have seen it.
Maybe one day.
Something vaguely similar that I have seen is massive congregations of phosphorescent organisms in the ocean on a dark night where each wave that broke was a glowing, luminescent, limey green explosion. That was pretty special too.
