My wife ordered the movie "Identity" and she was watching it while I was on this site. She said "Don't watch it". Most of the movie was just about the normal people are getting stalked and murdered by someone who they still haven't identified. Then she says this big multiple personality plot comes out at the end. She came upstairs and said very seriously, "I don't think you should watch this one." It doesn't deal with abuse issues, but it still is a big reality switch in the end. Not for guys for me with repressed (but barely) memories. Unknown flashbacks.
I remember watching "Primal Fear" with friends and being in shock after it. And that was five years ago. I still remember it. I just thought I should let you know that "Identity" is one to be avoided if you are still really trying to avoid your flashbacks.
