I cannot answer your question directly but maybe I have some information that might be helpful. I interviewed 110 people who had been unconscious about their experiences. Only 27% remembered nothing. The rest had these experiences while looking to the caregivers as being totally unaware.

Inner Awareness 9%, Perceived unconsciousness, 27%, Distorted consciousness 14%, and

Exceptional/paranormal experiences 23%.

I'm assuming the functionalities would be different depending on the state the patient is in.

Here's a course that's free to view that I wrote on the subject.

I've also written a book that has more detail entitled, In a world of their own experiencing unconsciousness that's available on Amazon.

Good luck with this project.

Dear Madelaine Lawrence,

Thank you for your valuable answer and suggestions.

I go through your provided URL and read the contents. The subject contents are very much relevant and informative. But, I wants to know some answers from you. Can you explain me please, if possible?

My questions are,-

1. Is it possible for a unconscious person to dream; as because mostly people dream in their subconscious state of mind (Sleeping state)?

2. What is the gap between near-death experience and death (Completely dead state)? How frequently unconscious patients feel their complete dead state?

3. In the situation of Out-of body experience, do the patient experience any spiritual hindrance? (Suppose the circumstances is like this - Suppose they feel their soul is outside their body and they were trying to recombine.) What are the obstacles they face in this situation?

Thanking you again.

With regards.
