Not sure I get you, but yes events can be buried, I am de-cluttering and came across some paper work that seemed to remind me of an event I do not remember.

It seems that we can ignore little bits, some we bury completely and others we can have daily reminders. Avoid triggers in a conscious way is a good technique, yet to avoid for the sake of avoiding does not help in the long run as you do not give yourself the power of choice. If you get me. I often do not get me.
