NC as outing.
I always write my dreams down if possible and have been doing so for about a year and a half. I dream about old friends a lot so this might just be coincidence.
A few years ago I was living abroad, and became good friends with someone I met there. She rings me long distance once every few months just to chat. Anyway 3 times I've dreamt of her, and she's rung me that day. Twice I've actually woke up from the dream to someone passing me the phone and saying "it's X ringing for you".
An elderly relative of mine who was a deeply devout Catholic nun died last year. Three times I dreamt of her and the following months, and she was unhappy. In one I dreamt I was at her wake and her dead body sat up from the bed and stared at me.
I went to the chapel after that, and put her name in the book of prayer requests (Praying for the souls of the dead is an important bit of our religion). I only dreamt of her once more, and she was happy and free.
I'm a total sceptic btw, but that's my experience.
