(1) The more you care about a person, the easier it is to appear in dreams. A strong desire to connect with each other leads to this dream. This is a dream that externalizes the anxiety about love. The person you secretly love often appears in your mind, so it is easier to dream about him. Do you really dislike him at all?
(2) If you can't communicate with someone you secretly love, it's easy to dream about him. This is because your subconscious has been suppressing your feelings for him, making it easy for you to dream about him. This is your subconscious way of releasing repressed emotions. You have a secret crush on him for three years, and you are the first person you like. You are very impressed with him. Although you don't like him now, your subconscious mind can't forget him completely, and it will still leave his traces. Only through dreams can all these once suppressed emotions be released.
(3) The person you once secretly loved left a deep impression on your subconscious. Now that you have love and a boyfriend, you will often think of your boyfriend or love. Although you no longer like the boy you secretly loved before, or you won't think about him, when your subconscious mind is aroused by love, you will naturally think of your feelings for him. Nothing, it's just that he has something to do with your love, so you dreamed about him.
In fact, this is just a general analysis of your dream. The most correct way is to analyze what appears in your dreams.
Dreams are the expression of repressed wishes in real life, and also the prospect of the future. Dreams are prefabricated or suggested by the subconscious mind. In fact, dreams reflect your reality. If you think about it carefully, you will know what your dreams tell you, and you will know what your subconscious is thinking. No one can really help you analyze your dreams, because no one knows your experience, your thoughts, and only you know why you dream like this.
