Yes I can relate! I especially feel like freaking out when I see old people eat!? Or if silverware scrapes the plate, or little kids yelling.

I ignore the phone and door usually because I expect notice first. I have a stong startle response which is from PTSD. If I'm at home and my husband walks in behind me I jump and yell. He thinks it is funny; I just feel like I'm having a heart attack.
