I agree with Tarotphelia, you may want to try to contact him via someone else you know.
It could even be that someone in his family has died, and you are picking it up but interpreting it as him.
It could be he is going through an intense time right now dealing with losses of his own, and part of him is dying in his expectations or hopes of life.
I had a similar experience ***
when i was in 6th grade I liked this boy. Ok, then we went our separate ways. At about age 18 I started having dreams about him. He was lost. He was hurt. His parents moved out of the house and didn't tell him where the new house was. Always he seemed sad and hurt.
This went on for years. I dreamt about him probably every week for about 10 years. I tried to find him in the phone book to see if he was ok, on the internet, I considered writing Oprah for one of those "meet the person in your past" episodes! Nothing.
One year I got a very clear vision that he was married and what the woman was like.
a few years ago I came across his name in the phone book and called. Of course he had no idea who i was, but he WAS married and the woman was similar to what I'd seen. he was living in the same state I was the year I had the vision. But he said he was fine. All those dreams of fear, danger, etc. didn't seem to apply.
I used to cry and pray for him all the time, i was so worried.
He didn't seem to have any issues.
Sorry for the long story, but all that to say, maybe he is on your heart because you need to connect to his soul for some reason, for you or him. Maybe he is in danger, maybe not. But it never hurts to offer up a prayer for him. Then try to get ahold of him and see whats up.
good luck! but just know, some things we never do figure out.
