"What causes or why do some dreams keep repeating themselves?

Dreams that recur (or repeat themselves) is a clear indication that some issue is not being confronted or that it has not yet been resolved. Your anxieties about a certain situation that you are struggling with may also cause you to have recurring dreams."

"What Does it Mean When You Dream about Someone?

To know, what it means when you dream about a person, we can make use of several theories for interpreting it. If it is someone you know, the most probable and common theory would be that you have been thinking about that person way too much. Specially, when you dream about someone, it is very likely that you were thinking about that person when you fell asleep. This creates an imprint of your thought on your subconscious mind, which gets reflected in your dreams. But, going by theory, when you dream about someone, it has more to do with certain aspects like their personality, or the relationship you shared with them, rather than the person itself. These people may appear as representatives of their qualities which you wish to inculcate, or else you already possess but are unaware of. If you are under a lot of stress, you might dream of a person who has been the cause of stress in your past, or someone who has led a very stressful life themselves. Whereas, seeing a favorite person or a peaceful personality denotes the peace and calm in your life right now."
