While you look in the (for me at the moment grey) sky, it’s almost like you don’t see just what you’d draw on a painting. It’s like a million (or so) tiny light particles flicker around. And in general it’s not like looking for example on the ground where you see everything ‚normal‘, looking at the sky feels more like watching something on an old tv.
What’s that?

Do they move about? Might be the white blood cells in your eyes

So you mean eye floaters? They are dead cells and such things in your eyes, which then you see. Completely normal.
> They can become particularly noticeable when looking at a blank surface or an open monochromatic space, such as blue sky.
Wikipedia explains it better than me:

Edit:
Probably not these but the other things that two people have linked. But I will leave this here, in case someone has same thoughts than me or have ever wondered what these are.
This is (probably) the [blue field entopic phenomenon](https://en.wikipedia.org/wiki/Blue_field_entoptic_phenomenon) (“entopic” means “on the inside”, in this case “inside of your eye”).
Your eye contains a bunch of blood vessels. You’ve probably seen them before at the eye doctor, when a bright light got shined into your eye, as a weird-looking web covering most of your vision. But under normal circumstances, adaptations in your eye and brain edit those blood vessels out because they’re always present. Specifically, since they’re filled with blood, they’re usually red, so your eye effectively says “okay, that area is brighter and isn’t as red as it looks”.
But once in a while, a *white* blood cell squeezes through those blood vessels. And since white blood cells are both big and, as their name implies, white and not red, they briefly let a lot more blue light through than the blood vessels normally do. So for a brief moment, the shadow of the blood vessel in your vision disappears, and the edits your eye and brain make to compensate for it make that spot look especially bright.
There are other possibilities that match what you describe, like [visual snow](https://en.wikipedia.org/wiki/Visual_snow_syndrome), but that’s the most likely reason.

As other people are saying, it’s possible eye floaters or white blood cells.
If you’re talking about the night sky, what you’re seeing is likely individual photos from far off stars and galaxies. There isn’t enough consistency or volume to resolve these little dots into single lasting points, so what you see is the static of a trillion stars, all shining their light into your eye. I see this phenomena too when looking up into the night sky.
