Could someone tell me what this dream could mean?

I dreamt about walking in my old school, and when I was walking there, there was this 35-40 man and his child walking around there. He seemed very agressive and he was yelling he wanted his 7up for his kid. I tried to hide at first, but then he saw me and asked me if I had a 7up with me, and I said no because I didnt, and then grabbed a gun and shot me. It sounds like a scary dream but it wasn't, it didnt even hurt or anything. The next minute I saw myself lying on the floor because I was actually standing next to it, but no one could see me. I felt peaceful and not scared or angry at the man at all. What could this mean?
