Death dream

I had a dream last night that I was in a hotel. I saw a little boy walking to his room, he's about five year old and he has a backpack like he was on his way home from school. Then the little boy walks down to the lobby where I saw him fall. I rushed downstairs and found him dead on the floor then woke up.
What does this mean? I never have dreams of people dying and I've never see this little boy...
