By all means talk to whomever is still alive about those days. History is many-faceted and different people will have experienced different bits of it. As said before, seeing Hitler was not that rare, whole schools were sent to wave to his open-car motorcade when he traveled through Austria after it had been annexed in 1938, and they probably had to fight for space with a lot of others wanting to see him. Remember that was a time when speaking to the masses was a required political skill as radio set saturation in households was far from 100%.
Living in a city that was bombed was certainly awful but I remember an uncle, then about 12 years old, telling me what an adventure is was for his friends an him, who ignoring the bomb raid sirens rather than going to a shelter, went out into the fields to watch dogfights between Allied escorts and German fighters and maybe even see a bomber crashing. For them it was just another adventure. (For those a few years older, it was more serious as they were drafted as auxiliaries manning flak guns, carrying ammunition, etc.)
Depending on what you saw it is quite understandable that you might not want to talk about it, although there are some books detailing such youth war experiences.
I regret not talking more about those times with my grandparents and parents when they were still alive, so I have to fall back on bits and pieces that surfaced occasionally.
