Can people really see events that are happening in a room where the are unconscious and their eyes are closed? Because of the out of body experience. Wouldn't this prove NDEs aren't just a side effect in the brain.

after your heart stops beating, your brain cells will die within 37 hours but still communicate until then ..

I've had OBE's without dying. Once conscious and the other times while sleeping. Plenty of people have. So, yes, it is possible to do and you don't need to be dying to have it happen.

Once in a car wreck, I actually had VERY slowed visuals and felt like I wasn't even my body, experiencing it from another view.

I think my instance might just be the creativity of the brain mixed with extreme circumstantial events.

It's been recorded and experienced countless times, a lot of the time in front of doctors.

People just tend to "keep existing" when their body and brain is shut off.
