Or is this just a crazy dream....

Last night I dreamt that and old, dear friend of mine that passed away almost twenty years ago found me. He didn't come to me, I was led to him. By that I mean I went to his "house" to visit. I could draw it, it was that vivid. We talked for hours about his life, my life, the family he left behind, every subject you can think of. I just  can't shake the feeling that is was more then a dream. Funny that it happened on the anniversary of my Mom's passing. Any opinons on this being just a dream or more?
