Dreams involving unresolved feelings for a crush often reflect your subconscious thoughts and emotions about that person and your romantic desires. The presence of someone in the dream telling you to give him a chance suggests that you may be seeking validation or advice regarding your feelings. This could indicate that you have an inner conflict about whether to pursue this crush or not.

The phrase "he's a nice guy" could symbolize your mind's recognition of his positive traits and might be encouraging you to consider the potential for a deeper connection. It might also reflect a desire for reassurance about the possibility of a relationship.

Consider what this crush represents for you. Is he someone who embodies qualities you admire or desire in a partner? Reflect on your feelings and whether you're ready to take a chance on potentially exploring this relationship. This dream could be a gentle nudge from your subconscious to take a step forward in your romantic life.
