What wrong with my dreams?

Ever since I remembered I have had dreams of people dying or having something bad happening, like for instance I dreamed about my friends getting into accidents and it would happen, well now that I'm older I had worse dreams like for instance my grandma, I had a dream one night that someone was having a heart attack the image wasn't clear but I knew what was happening well anyways the day after my dad calls me and says my grandma had a heart attack, and yesterday I had a dream of two people trapped in a house fire but I don't know who it was, so is there something wrong with me? Am I crazy should I go to shrink?
