If I dream about a man, who is thinking about whom: me about him or him about me?

It is impossible to answer this question without more information. Dreams are often symbolic and can mean different things depending on the individual's life experiences and personal associations. It is also important to consider the context of the dream and the emotions associated with it. Generally speaking, dreaming about someone can be interpreted as a reflection of your own thoughts and feelings about that person. If you are dreaming about someone else and they are thinking about you, it could be a sign that you have strong feelings for that person or that you are feeling a connection with them. Alternatively, it could be a sign that you are feeling insecure or vulnerable in the relationship. Ultimately, it is important to take the time to reflect on the dream and consider the emotions associated with it in order to gain further insight into the meaning behind the dream.
