Virtual Travel Into Nature for Individuals With Lived Experience of Severe Mental Disorders

The goal of the (observational or clinical) trial is to assess the use of the virtual application Toujours Dimanche for individuals hospitalized in a psychiatric care unit. The main questions it aims to answer are: * Is it feasible and acceptable for individuals currently hospitalized to use virtual reality during their stay? * What are the effects on mental health of the virtual reality application in individuals hospitalized in psychiatric care? * What are the barriers and facilitators of using the virtual reality application in a psychiatric ward from the perspective of service users and health care providers? Researchers will compare virtual reality users to control group (treatment as usual only) to see if the use of the application affects social and emotional well-being in the context of hospitalisation in psychiatry. In the first phase, participants will: \- Be invited to participate in focus groups to assess their interest in the application. In the second phase, participants will: * Complete baseline questionnaires on their connection to nature and social and emotional well-being. * Use the virtual reality application over a 15 day period alongside treatment as usual. * Complete post-intervention questionnaires and a survey on their use and opinions of the application. Healthcare provider feedback phase \- Healthcare providers working on the unit will be invited to share their perception of the impact of implementing the virtual application on the unit through surveys which will be sent by email.
