Was anyone else ever consumed by the thought of death when you are a child?

When I was a child, maybe around 5 to 7 (I don't exactly remember my age as my childhood memories are very vague and scattered) I remember thinking about death a lot. I remember having intense feelings of fear, loss, doom, etc. I remember thinking about how everyone dies and how we have no control over it, how I would eventually die and when it happens it would just be darkness whilst I rot in the ground (I didn't know cremation was an option at the time 😂).

I am wondering if anyone else here had a similar interest or obsession? It seems a very sorrowful subject for a child to ponder, but I really did think about it a lot. I even dreamt about it.
