Weird projection that I have never really been able to decipher

I had this dream a long time ago, I am 20 now and I was 9 or so when I had this dream. I still think about it all the time though and I'm not sure what to make of it. Anywhere, here's what happened...

It started off as a usual dream, kind of foggy and not really feeling in control of anything, just there for the ride. I can't remember what was going on, I was somewhere with my mom, and then suddenly we died (I should mention it was 9yo version of me in my dream so clearly I didn't actually die nor do I think it was a premonition of some sort), not sure what happened but I do know that we had died and I saw myself float up and away from my body. Then everything went fuzzy, gray, and I saw vibrating but I didn't feel anything. Suddenly everything became clear and I was on the ground down the street from my house at the time. Once I came to I realized I had just "died" and was in heaven, which I was really excited about. I remember running up and down the street and was happy to see my mom had made it too and was talking to some woman who I didn't recognize. Actually the street was full of people, walking around minding their own business, happy as can be. I specifically remember no one bothered to talk to me though, how nice of them haha. After I realized my mom was ok I decided to venture off and find my great-grandma who had died the year before this dream. I remember knowing that she was with my great-grandpa (who I had never met) and I wanted to go find them. Then I woke up, before seeing them :(

My own interpretation of this dream is that I projected and was actually on the other side, but I'm really not sure. I know that during my other projections I have experienced the vibrations, so that is kind of a flag for me that it was a project. I find it odd that no one bothered to talk to me, though? I mean I hadn't consciously remembered being there for 9 years you'd think someone would want to see me haha

I am also curious as to why my mom was with me? Is it possible that I brought her with me over there? Or was she there because it was a dream? So confused!
