I am so sorry you are experiencing this. The brain/mind /unconscious is so complicated, it take endurance and great therapy to figure out what the discharging of images actually means. It might take a lot of time to understand what the mind is doing, what the nightmares symbolize or indicate. There has to be that time taken and no rush to judgment, that time taken and persistent invitation to your unconscious that it is okay to relax defenses. I agree with everyone else T should not suggest memories or theories unless she is mirroring back something you give her first. Did you check out your ACE score?
