Not all bad dreams are bad. That's why it's advisable to ask people qualified to interpret dreams.
My bro was telling me this story the other day... I can't remember all the details but it went something like this.
A man went to a sheikh and told him he had a dream that his house was burning down, The sheikh told him to go and dig under his house and he'll find buried treasure.
Sometime later anothe rman went to the sheikh and told him that he had a dream that his house was burning down. And the sun was blazing in the sky.
The sheikh told him that he is going to suffer from some kind of loss (can't remember what). The people were mystified as to how two similar dreams can have entirely opposite meanings. So they asked the sheikh to explain why he gave one man good news and the other one bad.
The sheikh said the second man saw his house burning while the sun was blazing in the sky e.g. fire on top of fire meant more destruction/harm.
SubhanAllah, I wish I knew how to interpret dreams.
