A considerable number of intensive care unit (ICU) survivors report delusional memories, which refer to dreams, nightmares, paranoid delusions and hallucinations experienced in the ICU. These memories often have a strong vividness, long duration and high emotional impact. ⋯ The findings support the association between delusional memories and PTSD-related symptoms, but further research is needed to confirm their association with other psychological disorders. Development of a safety sense in the ICU can protect patients against the emotional impact of both delusional and stressful factual ICU memories. Appropriate follow-up of high-risk patients could improve their long-term psychological recovery.
