My grandma had an out of body experience when she 'died' during a bout of pneumonia in the 1930s. She said she was in a beautiful garden. In the distance she could see a crowd of people many of whom she knew but had died. They were behind a small fence. They smiled and said 'Hello'. She came to a gate but a man said 'You can't come through the gate yet. It's not your time. Your children need you.' She turned to go when suddenly she felt a terrific pain in her back. Apparently as a last ditch attempt to save her a doctor had punched a hole through her back into her lung to drain it. She swore this was what she had felt and it had saved her life but after that she was never afraid of dying because she said she knew what it was like.
When decades later she was dying...she would say for the second time....I was sitting with her when she opened her eyes, looked at the bottom of the bed and asked, 'Jessie, what are you doing here?' (Jessie died during the war). She then made me move off the chair so that Jessie could sit down and they chatted for some time. Well my grandma chatted...I only heard one side of the conversation.
I don't know if Jessie was really there or not but she was real to my grandma. Grandma died a few days later.
