What is the Meaning of my dream?

I dream of complete strangers in the west wearing three piece always.I am not present in the dream at all. In my dream is a family of 5,Mr.Grandpa(everybody calls him like that only),his son(I don't remember his name),his son's wife and his grandparents(one girl and a boy).They are rich.They have a party one night for some reason and at the middle of the night the grandpa climbs the roof.There is no ladder the roof is 30 feet high.Everybody calls him to come back down but he does not listen(He doesn't show any response).He goes near the smoke outlet and starts to jump and something heavy falls downstairs inside.Everybody asks what it is grandpa starts to show a figure of a rectangle and a hemisphere on top of it with his fingertips and then I woke up.
