Hypnosis to Improve Well-beings of Critically Ill Patients and Prevent Post-intensive Care Syndrome

The goal of this clinical trial is to evaluate the effectiveness of a hypnosis intervention in improving well-being at day 28 of an ICU stay. The main question it aims to answer is : -Does Hypnosis intervention at ICU discharge and on day 7 and 14 on the wards if the patient remains in the hospital, improve wellbeing at 28 days ? Researchers will compare discharged ICU patients who received standard post-discharge care to discharged ICU patients who received standard post-discharge care and hypnosis intervention on discharge and 7 and 14days after if they are still in the hospital, to see if hypnosis can improve their wellbeing. Participants will receive a hypnosis session on the day of ICU discharge, a second session seven days post-discharge and a third session at day 14 if they are still in the hospital.
