Dream of mother, person, died, friends, grandfather

So, it starts out in a sort of theatre setting, and my dad and one of my friends are pantomiming either a battle, dance, or both. Afterwards, my dad tells me I'm ready to see what's beyond this old-looking door I've never seen before. It was dirty and had multiple chains hanging loosely around it. My mother forbade me from ever going inside prior to, but my dad said I was ready to see what was there. As it opened, the other side was like a crypt; it was dank, and there was a heavy air around it and there were several coffins opened already. Oddly enough, most of the skeletons in the coffins were clean and ivory white, almost like the kind you would see in an anatomy class. Finally, we came up to a skeleton that was real (I figured so because it was filthy and looked like they were actually exhumed). It was my grandfather's (on my dad's side) bones, but I've never seen my grandfather, he died before I was born and the only person who talked about him was my dad. I stared at the bones for a while before my dad told me I had to pick through a few trinkets. The two things I picked were both blue; a metallic necklace with a jewel that resembled an eye that rested on my chest when I put it on, and a hair clip with two royal blue feathers sticking out. When my friend picked up the necklace, it was a metal peace symbol.
