Embarrassing reminders of the past
According to research, people who originate from traumatized families have an inbuilt drive to connect with the locations and events that gave their ancestors so much anguish. These people also have a need to relive those traumatic experiences. Such examples include the way that learning about catastrophes that harmed ancestors may trigger a strange and incomprehensible emotion of grief and connection in the descendants of those who survived the terrible happenings.
It’s possible that you may be left wondering why you’re so affected if you’re not aware that your generation has a relationship to certain traumatic events in previous generations. If you have little idea about the history of your family, this might be an exceptionally confusing situation for you. It is painful for many people, including the one who wrote this post, who have experienced something like in their lives. This type of stuff makes you wonder if maybe they had a distant cousin who participated in the D-Day invasion. The OP does not offer any background information on their family tree, but it makes you wonder if this may be the case.
