Remembering a dream at the beginning or end of unconsciousness is not uncommon nor are slight changes in eye color especially with glaucoma my eyes are much less blue than ten years ago....after the application of electronic sensors to various spots on the skull I ALSO DO NOT TRUST busy er staff to doubt every micro step in triage pressure

It would really help if you would post a link.

I think he met God..

Our brains are composed of three basic layers and the inner most part is the most primitive - our reptilian remnant brain.

It's this part of the brain that is responsible for suspended animation states. This sometimes activates when people fall into frozen lakes or rivers. Life saving mechanisms from our ancient DNA kick into autopilot inducing a kind of life saving coma.

Eyes can also change colour. One man involved in the immediate aftermath of the Chernobyl disaster, who was exposed to high levels of radiation witnessed his eyes change from brown to blue almost overnight.

And as for visions. The pineal gland, especially when deprived of oxygen during near death situations excretes a hallucinatory compound thought to elicit lucid dream type experiences.

I still have an open mind, but I'm guessing there's a scientific explanation.
