I wish I had a picture of this thing I saw, and I did try to video it, but then they hurtled very quickly out of sight.
Anyway, I will try to explain. . .
You know when you're up in a plane in the sky, you can see clouds in 'individual' balls? Well, it was about to rain yesterday and the sky was dark. Then suddenly I could see something like a very big, dirty, semi-transparent ball of cotton wool-like cloud hurtling towards me and over my roof. Then another, and then another. By the time I ran outside to try and video them, I could only see one very far off and it was going in a different direction.
The thing about it was that it wasn't like the entire mass of clouds moving across the sky, but it was like balls of clouds or gas, and they were just stumbling across the sky like they had been detached and blown away. And they were not looking nice or anything, but like a pocket of bad gas or something.
I have very little knowledge of science and I wonder if anyone is familiar with and can tell me what I saw?
