This is a sort of interesting 87-item list put together by somebody about the after-effects and changes occuring due to near death experiences. Some of my favorites:

• Can easily understand and become a part of abstract thought.
• A fascination with the sky, stare at the sky for hours.
• Mentally see complex mathematical equations
• Mentally begin to see patterns or maps of solar systems
• Automatic knowledge of ancient cultures
• A feeling of being huge inside, as if exploding in this most exquisite way.
• Make and keep extensive lists.
