HSAM + Mirror-Touch Synesthesia: Any Insights on Navigating PTSD When Both Are Present?

(Reposting after take down) I’m interested in any research, case studies, or even well-informed theories about the co-occurrence of Highly Superior Autobiographical Memory (HSAM) and Mirror-Touch Synesthesia (MTS), especially in the context of healing from PTSD or complex PTSD (CPTSD).

Understandably, I can’t find anything on how they might interact or how that interaction might affect trauma recovery.

I’m curious how having both could influence how traumatic memories are stored, re-experienced, or processed, and whether it requires different therapeutic considerations. Because this combination is so rare, I’m open to insights from cognitive neuroscience, trauma psychology, or clinical experience—even if anecdotal or theoretical.

I’d appreciate any thoughts or direction.
