I have dreams about a deceased brother who has been gone 30 years. I dream about him every couple of months. The dreams are similar, but can vary a little. I have not figured out why I dream about him like this. I don't find the dreams disturbing at all. I also dream about other people I've known who have passed. I do not believe in the dead visiting us. I think it's just our brains dredging up old memories plus making an interesting story line.
