well,in my country people belive that if you see in your dream someone's death,that means that that person it's gonna have a long life,so don't worry, i know it's horrible and sad but nothing it's gonna happen.
Sounds like a worry dream to me. Dont worry, it's one of them dreams ;), BTW i had a dream yesterday that the TV Exploaded like KABOOM! and it did! well... it didnt really go KABOOOM!, mais like pffff-pop. but anyway its broken :)
