I think it makes sense. I read the other day that dissociation is the child's way of separating the emotional and cognitive experience of an event so that she can do (the active behavioral aspect) what is required of her in the moment.
Reconnecting with the dissociated emotion and knowing requires facing head on what was too overwhelming to feel and to know in the past. All the dissociative defenses since then have been working to keep that overwhelm at bay, because there was no other known strategy for surviving it.

It is one thing to know that the 'way through' is to face that which was dissociated, and quite another to overcome the lifelong defense of fleeing it.
