I had a dream that I died

I had a dream that I died. The way it occurred was that I was in school outside and I had seen this suspect pull a gun out but I was so sure I wasn’t going to die, I’m not sure if it was my ego or the fact that I knew it was my dream so there was no way in my mind that I would have died. But I did, I was his first victim, and as he shot me I stayed in the floor in silence, no reminiscing of past events or previous memories just horrible noises of that suspect killing more people as he walked inside the school, I acted dead there on the floor in case he walked back, and he did with fear in my heart I laid there in silence. My vision slowly darkening up and I completely stayed still until I knew I was no longer there. I went to a so called after life, and it was kind of odd, there were cartoon characters there that played as souls that had passed away, all I knew is that we were trying to come back and reincarnate but in different bodies, but we never made it back. We were in a plane to come back to earth, I’m not sure if my mind wasn’t trying to make it in a way that I would understand what was happening. But I was sitting next to 3 humans, and the plane was filled with cartoon characters and humans. The characters looked thrilled to be in this new life. But I felt as though these humans were not actually humans but devils. There were these embodied individuals (devils) that were dressed as humans as we were sitting on the plane to come back to this life they kept asking me questions making sure I wasn’t trying to reincarnate, I did slip up they asked me something and I said “I’m excited to come back, I heard it’s like wall-e the movie” and that was enough for them to know that I didn’t belong. I woke up shortly after I’m not sure what that means. All I know is cartoon characters are my comfort shows/ movies ever since I was small and I still watch them till this day whenever something bad happens in my life. I’ve always been told I have a child like heart.
