Closet 
To see a closet in your dream represents secrets and private thoughts that you have been concealing from others. This dream can also imply that you are now prepared to reveal these previously buried qualities, emotions, or issues.
Locker
To dream of a locker suggests that there are things about you that no other people know about. Consider and take note of items that can be found inside the locker. For example, to dream of a school locker signify hidden feelings and thirst for knowledge.
To dream that you cannot open a locker or that you forgot the combination means that you are hesitant to take a stand in situations in which you are unsure about the outcome. In dreams where you cannot find your locker, this symbolizes your insecurities.
Cupboard
To dream that you are opening a cupboard implies that you are illuminating some veiled truth or secret.
Outhouse
An outhouse in a dream indicates that you have something you are hiding. You may need to open up to others or yourself to show your true emotions.
Backdoor
If you are inside a house or building when a backdoor appears in your dream state, you are most likely looking for an easy way out of a situation. People are more inclined to escape through the backdoor when they feel don't belong there in the first place or they prefer to stay reserved for personal reasons.
If you are outside a home or a building facing and looking at the backdoor, you will be soon involved in finding a solution to an issue that is unconventional or morally questionable.
