My mom’s root canal got infected and she died for 5 minutes. She said she saw a river or a darkness like a river and on the other side was just others. She didn’t describe what they looked like, but she knew it was others like her somehow. Then from behind someone touched her should and said “it’s not time yet”. Then she woke up and WOULD NOT STOP asking who just touched her shoulder. The doctors were all confused and kept saying no one touched your shoulder, you were just dead.
She became born again Christian after that and is a firm believer in Christ.
