Your dream is a reflection of your inner security.
But it also needs to be based on your own detailed life data.
You are a girl, if you are not married or have no boyfriend.
This dream reflects that you are afraid of the harm of the opposite sex in your life.
Being alone at home reflects your life state and is a little lonely. Night represents the time to be alone after life is calm.
The bad guys here can represent men's pursuit and their own emotional desires.
Trying to pry the door outside shows that this feeling is entering your inner world and making you feel insecure.
The door is also your inner door, subconsciously.
And you are afraid of being hurt, but you can't keep your heart quiet and have emotional fantasies.
