I dreamed my home exploded in fire, from attic to basement

In my home there are 2 floors to floor grandparents live, down floor me and my parents live and ground floor tenants live So i was in my grandparents room when saw a small cylinder and tinkered with it resulting in a gas leak later it caused fire in room since it was a small cylinder it was burst of fire then it calmed itself. Then my mother and i and Grandma got in the room to observe all the losses sat on chair in the room . That's when me and mumma saw the downfloor causing fire so big for a big 5 second out of the room we can only see fire outside, then mumma rushes panic and crying saying everything burned i went down too and saw it all dark and burned later my eyes openef & i realised its a dream.
