If you dream of telling someone an important warning, like their house is on fire, but those people ignored your warning, it means you have low self esteem. Your dream tells you that you are not respected and whatever you say is not taken seriously, if you are even heard at all.
It is a common dream to see imagery of a threatening scene, like a fire. You are running to inform your neighbors about this fire. However, they are not interested to listen to you. They don’t believe you.
