What is your take on this dream (part 395)

I often have peculiar dreams, but most of the time I can piece together which part of my day they came from. Part of the dream I had last night has me stumped. What do you think?
(forgive me if this is too verbose, but the experience of actually dreaming it precludes me from too swiftly summarizing)

So.. I’m standing at the position of attention facing 2 men who are about to perform some kind of ritual on a circular platform before me. Their garb strikes me as being from the renaissance period. One man places a peculiar red orb on the platform. The other man prepares a large, translucent, plastic-looking container that is very oddly shaped.. very non-symmetrical… It is also quite large. Inside of it are what seems to be plastic laundry baskets with the tops cut off. Then the strange part really begins…

The man with the container thing strikes the orb. (My thoughts within the dream are that he is about to melt this plastic to hear it sizzling as it falls to the ground). In a flash, melted plastic explodes into the air and begins raining down in a fiery storm. At first (I assume from being in shock) I think I’m alright with this happening.. but than a massive swath of fire hits me and I begin to run. As I run the melted plastic pieces become headless, flaming arrows. At one point I am struck by one of them and I feel the pain from it. Farther and farther I run hoping to find cover from the ever-increasing volume of arrows that are becoming quite dense. I can’t seem to find cover. I attempt to hide behind a tree to no avail. Spotting a thicker tree I break for it. All around me I hear the thud of the arrows striking the ground.

The dream continues but I fear I’ve already taken up too much space in the description.
