It really seems like that's most likely the case, that the trauma of Adam effortlessly cutting her arm off gave her Post-Traumatic Stress Disorder.

To be honest, I think part of why she had a trauma flashback when the glass broke is because she saw him on the news, thus he was on her mind. Trauma flashbacks happen when the person or their subconscious is reminded of what happened, and the triggers (yes, trigger is a legitimate term) don't always 100% make sense.
