A very freaky, confusing dream I had last night. Can anyone tell me what it means?

Last night I drempt that I was walking through a dark forrest on a small, dusty pathway. All around me were dead, mutilated bodies thrown about. I could tell that I knew the corpses from somewhere but I couldn't see their faces. I couldn't wake up. I wanted to scream but I was silent. I wanted to run but was strangely unable to move. I felt I was being watched. Like something was breathing down my neck. I heard moans and voices call out to me incoherently. Echoing through pools of blue. I saw my reflection but it wasn't my face. I couldn't see my face but I knew it wasn't mine. I started to feel like I was drowning. I couldn't wake up. There was no water around me but yet my lungs were filling with water. Not enough for me to drown but just enough for me to drown. I look back at the corpses hanging like mutilated scarecrows hanging crucified on the trees. I heard something call my name. I slowly turned around and saw a noose. A body hung from it bloody and lifeless. I couldn't recognize the face. I looked harder and finally realized it was me. I saw myself hung in a tree, bloody and broken. Then I finally woke up.

It felt like a trip down the rabbit hole.
I'm scared. This is the only dream I can recall that I remember in this level of detail.
Can anyone tell me what this means?
Please help me.
