Killer ents

I haven't been sleeping much lately, but I still remember a dream now and then...

I was driving down a narrow road somewhere in the woods, with a few vague friends.  We came upon a huge estate and a run-down three story Victorian house.  I'm not sure if it was our intended destination or not, but we got out and started exploring as night fell.

As I'm sure you can guess, it was a pretty good set-up for some kind of supernatural horror to start hunting us down.  Two of my vague friends disappeared, and were presumed killed by the strange apparition that first night.  We fled to the car out front, only to find it completely destroyed.

Forced to stay in the house, we explored the entire structure room-by-room.  Most of the rooms were mildewy and grey with dust and cobwebs, but we did find a few old guns in a broken case.  (somehow, they still worked and were already loaded)

The second night, the creature returned.  It came from the surrounding woods, and looked like a cross between Jason and a treant.  It had grown since the night before and towered over all of us.  In its knarled hand, it dragged a massive club that could have been a tree itself.

Another friend was crushed by the giant, and the rest of us were forced to retreat into the house.  This didn't deter the giant though, and he simply started bashing through the walls to get to us.

Then I woke up.
