Similar Astral Project Study
I don’t think this is the one you’re talking about, but it’s very similar.
It seems to be only mentioned in a few articles, but the researcher; Dr. Sam Parnia, seems to have published a book about his study.
Even if this isn’t the study you were looking for, I hope you find it interesting anyways. :) I’m glad to have gone on a little hunt for it, because now I‘m curious about this stuff!
That’s the one! The AWARE (AWAreness during REsuscitation) study and it looks like it started in 2008. And you’re right, not much online about it other than an interview in 2010 with Dr. Parnia saying that, based on his knowledge so far, near death experiences are an illusion.
Thanks so much!
