need answers- odd situation

I'm not sure if this is the correct area to post this, but am hoping someone might have knowledge/info/or even a guess as to how this occurred:

How is it possible that a young child (age 6) had, what I'd describe as an adult-level comprehension/understanding of an event/situation in the news?
I'm specifically referring to JFK's assassination and the aftermath- somehow processed it all as if I'd been an adult.
I didn't pick up anything from my parents or other older people, they didn't say much about it at the time.
