A bridge is a medium that connects a situation to another. Crossing the bridge will change the environment and situation. For example, a connection process that changes from a healthy life to a sick patient, from life to death, from consciousness to unconsciousness, to a state of perception is a dream about legs. Especially in the precognitive dream, the bridge is a typical symbol of the boundary between life and death. It is a nightmare that suggests death if the person who sings in a dream called by someone across the bridge is a dead person But there is no problem if it has not crossed the river. If it was a dream that reached the other side of the bridge, you should pay special attention to yourself.
