Yes, and that's backed by science. When the VA started running group therapy for PTSD clients, more often then not, the larger chunk of the group came out worse after sitting through groups where they talked about the specific combat events. It's been years since I read the reports, but my father was in involved in the study. There is a phase of atrophy where the focus needs to be on meditation (or something spiritual by choice) exercise and rebuilding. At some point, it may come up more often in conversation but never the grotesque harsh details.
