My uncle passed away January of 2011. Sometimes I still hear his voice and it wakes me up. Yesterday I had a dream about him and I woke up crying. I've been crying on and off since then. In the dream I walked up behind this man. The man turns around and it's my uncle. In the dream I knew he passed away so I was rather confused at that point. There was a white rail between us. So he walks up a white ramp to get to me and hug me. He stopped by the rail on the right hand side and people were passing him by. I looked over at him and he was just starring at me. He had red around his eyes and I think he was crying. We never said a word to eachother in the dream. After I noticed he was crying I woke up and that was the end of it. I don't know what this dream means. Just seems like he wants me to do something?
