Yes, the memory of the attack event with extreme bouts of fear coupled with delusional visions and a complete lack of awareness of anything other than the attack are hallmark symptoms. Eating, drinking, going to the bathroom, etc. don't even register. It's as if the person suffering has lost all touch with reality.

These are the extreme examples of someone "reliving the event", which is a natural part of healing, in an attempt to overcome and resolve it.
