I'm 16 now, but I remember when I was in kindergarten and my dreams weren't usually normal.
Of course, I would dream of being a princess, saving animals, or being in different dimensions like a normal child, but I also dreamed of constant death and suicide.
Death: This day was so clear to me: one night I was sleeping with my mom. She explained to me when people die, they fall into an eternal-like slumber and move on to a beautiful place above clouds (how it's explained to a child in her terms). I was deeply moved yet terrified. As a 6-year-old, I worried and even cried about not living in my own house anymore, never seeing any normal human being ever again, not eat my favorite foods or play with the latest games, breathing the same air! Death still haunts me to this day, but I've accepted it because I know that the soul moves on from its physical body.
Suicide: My parents would always fight almost everyday. Not anything serious like domestic violence but useless squabbles most of the time. I never thought of suicide like wrist-cutting or hanging, but in a form of running away from home or getting hit by a car. I wanted to have actually be hit by a car when I was 5-6 years old so I could escape the pain plus the bullying and racism that I was experiencing during that time.
Aside from that, I was a pretty stable child and grew up to be a unique person whose a bit on the crazy side

(which is now)
So back to the main question: was this normal? Maybe it's just a silly fear that little kids think too much about and move on?
