Another weird one

This dream started out with me and my brother sleeping on bunk beds, him on the upper and me on the lower. We were talking about something that I can't remember what it was but we were kids I would estimate me being about 5 and my brother about 9. Suddenly, as we were talking, my brother pulled out a shotgun and I was surprised as to why he would have that at such a young age. He kept saying we need it when the time is right. Just at that moment, there was a pounding on the front door of the house where we were staying at. My brother handed me the shotgun and told me to shoot once he opens the door. Although I was 5, I could hold it pretty well and was there waiting. My brother opened the door and I was instantly shot by someone. I could see figures outside but not clearly and my vision started getting blurry. My brother was shouting for me to shoot the grass outside so that we could find what was buried there. The figures were getting closer and just as they reached the threshold, I fired and it hit the ground just outside. When the shot hit the ground, a big hole started opening up and I could see it was like a barbecue pit with red hot glowing coals and pinkish/yellow flames dancing around. The figures instantly disappeared and my brother and I jumped into the barbecue pit and started digging with our hands and branches, anything we could find. After a while of digging, I told my brother that we aren't going to find anything, then he was inclined to agree so we went back out of the fire and started walking toward the front door when all of a sudden a vision crossed my mind (in the dream) of there being a box with really old US dollars buried in the hole. "Did you just get that?" I asked my brother. "Yeah," he said. Then we ran indoors and got some shovels and picks and started digging more. Just as a light started breaking through the bottom, I woke up.

It didn't but when I woke up I felt like I won the Lottery but then realized it was just a dream...
