yes

I have learned too that it can be "little things" shown that one does not think has a significance to the bigger picture but when I then find out such place has existed or that tool has existed it is validation.

lots of people have memories of being soldiers at war. It is the classic where there are so much feelings around and you kill people or/and are killed yourself, so it goes quickly and when it goes that quickly it is more difficult to take in, so it kind of follows you. Make sure you are protected from not seeing anything bad, that you won't get too close too fast. You may have flashbacks in the nearest.
