How to make glowing rain/mist?

So I've been playing Xenoblade Chronicles 2 and one of the effects that is used through the game (and the series really) is that ether (the game's version of mana) can often be seen floating in the air like a kind of glowing rain / mist.

Unfortunately it's an effect that's difficult to see in screenshots and I can't find a good one of what I mean, this is the best I could find (from the original game);

But as for the actual question; is it possible to have a relatively scientific reason for such a phenomenon?

What I want is;

• Some kind of glowing particles / droplets in the air. They could hang like mist or fall like rain, I'm not particularly bothered.

• Comes and goes, so not permanent.

• A reasonably widespread effect, comparable to weather.

• Can happen day or night.

• Happens in the lower atmosphere (so near the ground where people are and can interact with it, not lights in the sky like the Aurora or shooting stars)

• Something that occurs naturally (or at least isn't specifically triggered, so no one is pressing a button to make it happen, it could be as a result of human activity)

• It's safe. So nothing radioactive or hot that's going to kill everyone exposed to it for more than a few minutes or anything like that.

So is it possible, and how?
