YES, one can experience a lot of emotional flashbacks when they suffer from PTSD. This can also be the case with other diagnoses like depression and other anxiety disorders. A lot of people think that their experiences are not bad enough to warrant a ptsd diagnoses, but there really is no true measure when it comes to a "bad enough" when it comes to PTSD. The point is that something was bad enough in your life/past where you developed the sensitivity that PTSD presents.
