Reocurring childhood goblin dream

I believe this dream started at the age of 7, and ended at about 10. I had it probably about 4 or 5 times. From a first person perspective, I am walking around a bustling city, resembling a rainy glasgow or London, and there is a lamppost in the middle of the road, from which I pull a flyer. The dream cuts to me and a crowd of around 10 tourists, who are aged from 15-20, and I join them as a group for no apparent reason.

We wander around a small room with hundreds of large sculpted faces on the walls, with no entrances or exits. The faces are spiky, with wide and exaggerated features, most notably a large toothy grin on each, and even for goblins they look extremely sickly and senile, despite their pudgy builds. A large fleshy chute opens up in the wall after a few minutes, detailed like something from a H.R Giger painting, and the group slides down it followed by myself. 

The next room is almost identical, but the faces are much larger, they now are moving their lips too, bllinking harshly, and flickering long wet tongues. As we file into another chute, I see that much of the group is missing. The new chute is porous and stiff, and hundreds of hands begin to jut out and tickle me as I scream. The next crampt room is crowded with humongous goblin faces which scream and cackle at me, and a group of naked elves dance on the ground.

I dive through the next hand filled chute which spits me out into a graveyard, filled with short, stocky goblins. It is the dead of night, and a gigantic muscly hunchback goblin topped with a crown emerges from the dirt. He bellows "I am the goblin king, and you will die". I am suddenly armed with a gleaming sword, and the goblin king charges at me, swinging a devastating haymaker that slams me into a gravestone. I get up from the rubble and leap past his next attack, jumping off of a tall crucifix and driving the sword through his nape. He sinks to the earth and I dawn the crown as a mass of goblins bow down at my feet. Coolest dream ever.
