Intrusion symptom

What it means

Unintentional re-experiencing of a traumatic event involves symptoms that typically include sensory impressions and emotional responses stemming from the trauma. These symptoms seem to lack a sense of time perspective and context.

Vivid intrusive memories, flashbacks, or nightmares are typically accompanied by strong and overwhelming emotions, such as fear or horror, as well as intense physical sensations.
