My friend is still sick

Last friday we went langlaufing. It's just like skiing, but than without a mountain. And we were going up a hill and everything was covered in snow and the sky was totally white because of the clouds and there were a few leaveless trees around us and the only thing made by human-beings we could see was a church with a cemetery surrounding it and then suddenly my friend was like "This is kind of scary. It feels like all of the colors have been pulled out of the world and never going back again. And the human beings are going to forget the colors and after a while they will fade away because of it." she said
And then I said "you're sick." 
"Welcome to my brain." she said. "And then all the people will turn into zombies and they will eat each others corpses."

Now we all know how the world will end
