Short Stories with Tragic Endings

Me and two other people ( one guy and one girl ) are in a house, investigating
something I think. There is a particular room in question that we are going to search.
It is a small room. The three of us searched the room in turn and had some sort of
bet going to see who could find the most expensive quantity of what could only be
described as loot. I was the first to go. I don't remember what I got, but then the girl
went and found every single stone/jewel in the place. After she was done the dream
shifting to her sitting at the table with me standing there watching as she was examining
the gems going through each one scrutinously with the masterful skill of a jeweler. She
knew everything about each of the jewels and thew several away because they were fakes.
I remember her saying something about each one but I don't remember what it was. Next
the guy went. He reminded me of a friend from high school, Dave. He went through the
room and I seem to remember him finding a go-kart. A short while later, the dream
ended.
