PTSD - Nightmares for months

A few years ago I drove into a street where just before a fight had escalated. A man had killed another man. When I drove into the street, the killer looked me straight in the eyes and pointed his gun at me.

I made a submissive gesture with my hands and head behind the wheel. The man looked at me, stopped pointing his gun at me and ran away, leaving with me with a strong fear reaction.

I had nightmares for months. It was very traumatic for me. Because I kept having stress- and fear symptoms, (like nightmares, fears, worrying, stress and tension, and compulsive reliving the traumatic experience) I looked for a psychologist and went into therapy. This helped me to process this traumatic experience.
