Dreams about receiving messages from someone significant can often reflect your feelings, thoughts, or unresolved issues regarding that person. In your case, dreaming about receiving a text from someone you were dating may indicate that you still have lingering feelings or thoughts about him and the relationship.
The content of the message in your dream—his confession of still liking you and wanting to reconcile—might symbolize your desire for closure or clarity about your feelings and the relationship. It could also represent a wish for reconciliation or at least some form of communication to address any unresolved emotions.
Waking up and feeling as though the text was real suggests a strong emotional connection to these feelings. This could be your subconscious mind processing your experiences and emotions related to the relationship.
Consider reflecting on what you truly want moving forward. Are you open to the idea of reconciling, or do you feel it's better to maintain no contact? This dream might be prompting you to think about your own feelings, desires, and what would make you feel fulfilled in your emotional life.
