"Denial" typically refers not to the denial that something bad happened to you, but to not see how you act it out on others (or yourself). It is exactly those in denial that would claim that they "have moved on", and try hard to make it look like they did also to those around them. It then shows up in violent tendencies, lashing out against kids, enemy images, patterns of avoidance, psychosomatic symptoms, burnout, addictions, obesity, sports injuries due to overdoing it, inability to sit still and listen, etc. - not necessarily PTSD symptoms.
