- Thinking a lot about the illness, injury, or procedure (unwanted, intrusive thoughts)

- Feeling distressed at thoughts or reminders of it

- Having nightmares and "flashbacks"

Intrusive thoughts / memories: "The image of my son getting a spinal tap frequently pops into my mind."

Feeling the event is recurring: "At least once a day, I have a flashback to the accident. It's like it's happening all over again."

Distress at reminders: "To this day, I still can't stand the antiseptic smell of hospitals" OR "My heart races every time I hear a siren."

Distressing dreams: "The other day I dreamed that I was in the woods lost, and the doctors and nurses were hiding behind some trees."
