One interpretation of a fire escape in a dream is that the person is escape the fear of their daily life and to move on, which is why fire escapes are often shown in movies and books as a way for people to leave what they don’t want any more. The person may be trying to escape from an unhappy marriage or from overwhelming responsibilities. Another interpretation is that the person needs to slow down and take care of themselves, so that they are not burning out.
Also, seeing a fire escape in a dream signifies danger. For example, people in the dream are running for their lives and see a fire escape to save themselves from their near-death experience. The fire escape, in other words, is a representation of when one is faced with danger, but manages to get out of it.
