Sound and Vision: A collaboration between service-users, artists and the public to explore the lived experience of hallucinations
Hallucinations refer to the experience of hearing, seeing, feeling, tasting, smelling, or sensing the presence of people or things that other people do not. Hallucinations occur in a wide array of psychiatric, neurological, and medical conditions, but many healthy people may also experience hallucinations at some point in their lives. Research studies estimate that 3–13% of the general population, depending on the age group studied, have experienced a hallucination during their lifetime. This suggests that up to 1 in 10 people may experience a hallucination at some point in their life. But what are these experiences like? And are they similar to hallucinations experienced by people with a clinical diagnosis? Our aim is to develop a better understanding of the content and quality of hallucinatory experiences in the general public and how they relate to life history and sociocultural factors. We would appreciate your time in filling out our survey to help us reach this goal. The survey will take 15-20 minutes to complete. During the survey, you will have the option to upload any artwork (files up to 1MB in size) you have created about your hallucination or hallucination-like experiences, if relevant and if you are interested.
Who can take part?
Anyone can complete the survey, whether or not they have experienced what they would call a hallucination. There is a spectrum of ways in which the sensory world is perceived and felt. We are interested in the natural diversity of sensory experiences.

You can exit the questionnaire at any time and your answers will not be saved unless you complete all the questions.
What is the survey about?
The survey aims to understand the diversity of hallucinatory experiences in the general population, such as the quality and content of these experiences, and the circumstances in which they arise.
Why have I been chosen?
You have been asked as a member of the general public to consider whether you would be happy to participate.
Do I have to take part?
Taking part is entirely voluntary. If you do decide to take part you will be free to withdraw at any time without providing a reason, and with no negative consequences.
What will happen to me if I take part?
We will ask you to complete an online survey. This will include questions about your demographics, your mental health history, and the quality and content of sensory experiences, related to how you hear, see, feel, or think.

Are there possible disadvantages and/or risks in taking part?
There are no risks in taking part in this survey. It will however take 15-20 minutes of your time.
What are the possible benefits of taking part?
You will contribute to a better understanding of the quality and content of hallucination-like experiences in the general population, which we hope will raise awareness and challenge stigma around the experience of hallucinations.
What will happen to my data and to the results of the research?
Your responses to the survey will be anonymous, which means that no one could use any reasonable means to identify you from the data. As your data will be anonymous it cannot be withdrawn because we will not know which data is yours.
The anonymous data collected will be stored securely on the University servers and only the researchers will be able to access it. The data will be analysed as part of the research study and then results will be written up for project reports, publication in peer-reviewed scientific journal, and/or presented at conferences, and shared with academic collaborators. After the project has completed the data will be retained.
