The swamp was gloomy...

I had a dream about a year ago where i was walkin to my home in this gloomy and foggy swamp. Everything was tinted blue like in most horror movies. I walked up to the entrance to my home which was just a door standing alone. I unlocked the door and walked through to see a tree house with a metal spring loaded ladder. I climbed up and went inside. As soon as i stepped in sharp wires came from everywhere and sliced me into pieces. The dream then continued on but i've forgotten the rest. This part really stood out.
