If you have dreamed that the key was broken while opening the door in your dream: Changes in your agenda towards the evening may affect your plans, your habit of acting too cautiously may prevent you from enjoying life or cause you to miss out on the fun. Breaking the key while opening the door in a dream is a symbol of obstacles in front of you. It also portends that you will not be successful, that you will be defeated, that you will be in trouble. It is a sign of difficult times.
