I saw a strange dream last night. It was about a virus or something.
The dream started with me being at my friends place. It all happened in winter. We were bored so we turned on the TV. There we saw a news broadcast about some unknown infection. Don't remember well but I think that the infected had deformed hands and legs. Looked like gangrene. All uninfected were evacuated and the dream ended when I got on the train.

Why did I write it here is that I got this future prediction kind of feeling from this dream and I'd like to know what could cause these symptoms.

you say it happen in the winter? could it possibly be frostbite? gangrene and frostbite turn the affected area black.
