I presume it must take enormous mental effort to keep suppressed such traumatic and so in one sense highly memorable events. It must almost be like being left in a house alone after having just had a limb hacked off and then trying to convince oneself that it never happened successfully suppressing all the pain, making oneself completely unaware of all the spurting blood, trying to act normally with no consciousness of physical disability. If one could achieve that, it would certainly lower the mental trauma but it would be highly undesirable. Life-saving procedures stemming the flow of blood, phoning an ambulance, and so on hinge on admitting to oneself that one is seriously wounded.
So it is when we have been emotionally wounded. Suppressing awareness of the wound initially seems easier than acknowledging that we need help, but to do so is dangerously unwise.
I mentioned a woman who had bizarre dreams that seem to be an accurate replaying of what had actually happened to her in real life as a child. These events included being shut in a coffin filled with spiders, and ceremonies involving people wearing weird cloaks engaging in child sacrifice.
