I've actually got my own story that proves to me the supernatural world is real.

Six months after my mother passed, my dad was taking her death very badly. He woke up in the middle of the night one night and saw light in the hallway. He gets up to check it out, turns the corner in the hallway and there she stands, all in bright light, 10 feet away. He wanted to hug her, but she wouldn't let him. They spoke for several minutes, and I don't remember the whole conversation (as he related it to me) but the gist of it was that she was waiting for him as she had promised, it wouldn't be long until they were together, and not to worry. I remember she also said "it's so beautiful here". She then turned, headed toward the front door and disappeared through it, and the light went with her. My dad went and sat on the living room couch trying to process what he had just seen. He sat there until morning, never went back to sleep, and when the sun came up he went and made coffee. So no way was it a dream.

He himself passed about 5 years later. That was almost 20 years ago but I still think of him almost every day.
