Dreams featuring someone you know can often reflect your thoughts, feelings, or experiences related to that person. Since you mentioned that he doesn't do or say anything specific in the dreams, it could indicate that he represents a certain quality or emotion for you, rather than a direct relationship.
Consider the context of your life and any recent interactions or thoughts about him. Are there aspects of your relationship or feelings about him that you are processing? Alternatively, he might symbolize something else in your life, such as a desire for connection, unresolved feelings, or even certain traits that you admire or wish to embody.
Reflect on your feelings during these dreams and any significant events happening in your life. This might provide further insights into what he represents for you and why he keeps appearing in your dreams.
