Can I use the example of somebody that's being sexually molested as a child.  People very often will block out their experience or they will come and sit with you and tell you that they don't even remember positive things about their childhood because they block out the negative experiences.  Then at the age of 20 or 15 or 39 I've had them, women and men at all ages, who will then come and sit and then they have a breakdown and then I will diagnose them as suffering from post-traumatic stress because they have all the symptoms.  They have flashbacks, they have nightmares, when they eventually start, when that thing breaks, when that boil breaks to the fore those are things that happened years and years ago and yet at that moment something just a little bit extra, some sort of element of stress just causes them to break down and they become unable to function as human beings for a while, and it's a long process where you have to build them up again.  So I don't know if that comparison maybe answers your question.
