(Armchair psychologist here) The absence of perceived trauma while still in the environment that can produce similar traumatic experiences is normal and makes sense. You are adapted to your environment as a child. But, once you leave the said environment for something safer and more comfortable (note that it’s a historical anecdote, not many people could do that say 150 years ago), you also face the need to re-shape your identity in a way so that you can thrive. This points out to you the fact that previous experiences were in fact traumatic and need to be emotionally processed, re-lived and understood in a way.
