Yes. I've done a lot of reading on the subject trying to explain and begin to understand how the incredibly positive changes I've experienced come about...and "reverse PTSD" seems remarkably close. A guided, safe psychedelic session is similar in that it's a one-time, extremely powerful event that causes a lasting change in the brain--except in this case it's positive and intentional* whereas PTSD is negative and wasn't sought out. * There seems to be a large degree of choice in which changes one wants to take away from the experience but this is a highly subjective, personal conclusion.
