Dreams And What They Mean

I don't know what my dream was about the other night (Tuesday) but it has been bothering me it was so real, dad came back I hugged him he felt like he did at the funeral home, cold so cold, he was sitting on the couch, I was happy to see him we all were but we were so angry at him, I could feel the anger inside of me, when I woke up I could still feel him and that anger I had towards him in the dream... it doesn't make since what could it mean, I won't even go into the other dream I had that night that was just very weird.... if anybody can interpret dreams let me know what it could mean, I have gone though my anger stage that is why I don't understand this dream, that is the first stage I went though....
