Cross-cultural study exploring near-death experiences


Dear Sir, dear Madam, 

You are agreeing to participate in a study concerning Near-Death Experiences (NDEs).

In 2000, the American psychiatrist Bruce Greyson, one of the pioneers in the scientific study of NDEs, defined these experiences as: “deep psychological events including transcendental and mystical elements, typically occurring in individuals close to death or in situations of intense physical or emotional danger”. These experiences may, for example, include a feeling of intense peace and well-being, a feeling of being outside of one’s physical body, seeing a bright light, an altered perception of time as well as entering a non-earthly world. Many other dimensions can also be experienced, such as encounters with mystical beings or vision of deceased people.

If you think you might have had a similar experience, we would love to know more about it!

The objective of the study is to collect data in countries around the world, with the aim of comparing near-death experiences reported by different individuals.

We therefore invite you to describe your experience in written form and to answer a series of questions aimed to better characterize your experience. This study is anonymous, and individual information obtained will be protected and remain completely confidential. The results of this study will published in a scientific journal and presented at scientific meetings. For any further information, please contact us at this address:

You can, of course, take all the time you need to answer the survey. However, please note that if you wish to stop at any moment and continue later, there is a “save & continue” option at the top right. This will allow you to save your answers so far and resume later. You just need to write down your email address (which will not be sent to us by the website). However, we advise you to choose a time when you will be able to complete the questionnaire in one session. You should allow about 30 minutes.

Please note that our survey exists in other languages too (French, Dutch, Italian, Russian, Japanese,...), you may change it on the top right of your screen. 

Thank you in advance for sharing your experience with us!

Dr. Martial, Géraldine Fontaine & collaborators.
