Yes. When something happens to us that is beyond what we can emotionally handle, our mind attempts to protect us by blocking the event from our awareness. This type of blocking, called dissociation, can effect our memory of the event itself and also the memory of the emotional and/or physical sensations we had at the time of the trauma. In other words, we can feel frightened or depressed and not remember why. Alternatively, we can remember the details of a trauma but have no feelings about it. Or, we can have “body memories” of the event, but not remember the event itself.
