There's a reason why hypnotically-induced recollections are generally inadmissible in US courts. It's a similar mechanism at play, here, with recalling traumas. Memories are extremely unreliable to begin with, then you take into account a large passage of time, then you start monkeying with them like that with something that isn't reliably clear to begin with, or something pops into your head that hasn't consistently been there.
I don't think 100% of cases of trauma recollection are bogus, though I wouldn't be inclined to believe extraordinary claims in any given case without additional supporting evidence. The guy claiming he was nearly kidnapped in childhood is extremely likely to be lying for attention or extremely misguided.
