I find that my nightmares and flashbacks help me in my therapeutic journey as well. I also find that the information becomes available when I'm ready to work on it. My flashbacks are traditional - I'm there experiencing the event and it is totally real. I don't want anymore flashbacks ever but when I am triggered it sometimes happens. I think - and ignore this if it doesn't fit- that you should honor yourself and not try to push for more. I really think it will come up when you are ready to see it. And a trauma therapist might be better for this than a life coach. I'm not saying the life coach isn't helping, I'm only saying that a trauma therapist can be so much more helpful along with a life coach.
