Well this is pretty late but I had written half of a Halloween fanfic that I wanted to publish but I couldn't. Here is some of it. Btw its a band fanfic so I hope you look forward to next Halloween!
(This is in Kellin's POV btw)
After grabbing our supplies, we started our journey through the forest. I have to say that the forest was one of the eeriest places I have ever seen. The trees had lots of leaves but there were a few dead trees here and there. But also, the dark skies made it hard to see very far. The smell of fall leaves had come through well, but what ruined it was the stench of mildew from the rain. The air in the forest felt so cold as if someone had just...taken its soul from the forest itself. In the distance I could hear screeches from who knows what and the slight whistle of the wind. Before we knew it, we were at the house that was a popular topic around Halloween. It had black timber on the outside of the house, which shone a midnight purple in the moonlight. You could tell it was worn down because of all of the timber missing from the exterior.
