What do the things in my dream mean?

I have dreams of myslef walking down large stone steps. To either side of the staircase there are no walls, just mist, and beyond that I can see a never ending darkness. I hear a small soft almost cheerful or uplifting tune but when i wake up I cant remember what it sounds like. I am absolutely naked but the mist seems to cover my penis and for some reason my chest as well (which I have always been uncomfortable showing in public). I carry in my hands a large shiny axe, sometimes silver, sometimes purple, most times black. i know there is something in the mist, almost a ghost like snake women creatures, many of them flying around me creating the mist. what does it all mean?
