Last night I had one of those cool and very elaborate dreams that feel completely real. In a nutshell:
There was some kind of animal pandemic going on, affected animals (mammals) started to get scruffy fur, their gums and teeth turned gooy-black and it also affected their brain. Animals would roll eyes and where you would expect the white eyeball was a new eye, dull-red and with no pupil nor retina. When that happened the animals started to act like possessed and moved around in a creepy twitchy yet controlled way.
People in hazmat suits captured those animals and killed them by the thousands, cats, dogs cows, everything, some were locked up in high security vaults in underground mining tunnels. Apparently there was a high danger of that sickness spreading to humans, or maybe that had already happened, it wasn't clear in my dream.
It was pretty much an end of the world scenario though, the sky was black as night from the fires they used to burn the animals alive, the fields were barren and everything was dark and monochrome. I remember I touched a sick cow and the rest of my dream consisted of a super long sequence of desperately washing my hands with a blue disinfectant.
I enjoy those dreams, they're like my own personal horror movies.
