About this symptom
Intrusive memories are recollections of a traumatic event that arrive without being sought and are difficult to stop. They are not the same as ordinary remembering. People often describe them as vivid, immediate, and carrying the emotional and physical charge of the original experience.
They may be triggered by something clearly connected to the event, or by something apparently unrelated: a smell, a sound, a time of day. Some people experience them as images, others as sensations or emotions without a clear picture. At their most intense they can feel like a partial reliving of the event rather than a memory of it.
Intrusive memories are among the more distressing features of post-traumatic stress, and they are frequently followed by efforts to avoid whatever seemed to trigger them, which can gradually narrow daily life.
This is a recognised response to trauma, not a sign of weakness or of remembering wrongly. Trauma-focused psychological therapies address these experiences directly.
