Why did I dream this?

Ok let me start at the beginning. My 15 year old nephew was murdered a month ago. He was shot in the head. I live in NC and he lived in Ohio. The funeral was by far the worst one I have ever been to. Im sure because he was so young. Anyways, last night I woke from several dreams. In some of them, I was at his funeral, others he was right there with me... I just hugged him and cried and told him how much i love and miss him and he said he knew... I knew he had to leave again. At the dreams with the funeral I was with his mom most of the time as I was at his actual funeral. What do these mean? Also when I ask him what happened that night is when I wake up. I had also asked him one night to send me a sign that he was ok and that he was with us. i went on pogo.com and was playing a word search adn hit random puzzle... some of the words that came up were : Gun, Shot, Jury, Trial, ... the woman is out on bond and the trial can take a long time to begin.. is this his way of contacting me or am i reading way too much into this?
