Dream of children

I dreamt I walked into my own living room, my children were with me and 4 other people I had never met. My oldest daughter pointed to the man sitting on our couch and asked who is he? I looked and he was a skeleton that slowly made himself human. One of the other people said oh he is dead, the man looks at me and says hello I am Richard. It was so vivid and real and still gives me chills. I have no idea who these people were.
