It might have been me that mentioned being trigger subconsciously with PTSD.

Since so much of PTSD is working at the subconscious level, it is important to have a therapist who is expert in PTSD. The doctor has studied the subconscious extensively, and understands how to help you cope with PTSD.

How does one know if the triggering is on this level? The T teaches us how to recognize OUR FEELINGS and OUR ACTIONS that result from being triggered.
There are good triggers ...ones we use to comfort ourselves... often smell (and often food scents!) ... places we go for "vacation".... etc. Hypnosis uses subconscious triggers to help someone quit smoking, for instance.

One of the ways we learn to cope with PTSD is by identifying these feelings and actions: that they are happening probably because we were triggered. Once we can begin to note when or where these feelings happen, then we are on the way to identifying the actual trigger. This might never happen.

The good news is, that due to PTSD events, ppl, memories are not FILED properly, but the brain tends to MISFILE similar events in the same place! WHy is this good news? Becaue once you are able to REFILE an event in it's proper place in the brain, often the brain REFILES all those that are MISFILED in the same place and relocates them to the proper place. So not all events, triggers etc need to be identified etc.

Once we can stop and recognize that we have been triggered, then we can begin with the coping of "it isn't happening now" " I am safe now." etc reframing that the T will give you.

I hope this explains what I was talking about.
