Thanks everybody for answering me.....

Well....I got my answer today to my dreams....Not a happy ending!
My uncel passed away just couple of days ago....so, that means my grandma and my ants were waiting for him! He is his son and her brother!

My sister called me today to tell me the news, and then I told him I knew something is happening because of my dream....when I had that dream I called my parents next day and they said everybody is okay....

I don't have dream of dead people at all....This was kinda my frist time!
