thoughts on the dead.. can we speak to them in our dreams?

Date: 2/3/2017

Once in a while I dream about a man I loved.. he shows up in the same dream as the other people in my life who have passed on.... always a motel looking building in a desert... really broken down but full of souls. I feel like I am accessing "purgatory" in my sleep. He tries to chat but I am so concerned with telling how to avoid his death and it hurts him so he says "I'm gonna go home" and I think his spirit returns to his family. I wonder if we really can speak to the dead in our dreams?
