For it was really shown that these memories correspond to traumas which were not sufficiently 'ab-reacted,' and on closer investigation of the reasons for this hindrance, we can find at least two series of determinants through which the reaction to the trauma was omitted.

This is the case when a trauma, in itself effectual, occurs in a state of a severely paralyzing affect, or from a transformed consciousness. But it may also happen that the psychic trauma evokes in many persons one of these abnormal states, which in turn makes the reaction impossible.

Hence, we can say, that the reason why the pathogenically formed ideas retain their freshness and affective force is because they are not subject to the normal fading through abreaction and through reproduction in states of uninhibited association.
