Me and one of my really close guy friends were dating, but in real life everything is completely platonic. My good friend really likes him, and even in the dream I knew that I betrayed her.
Dreams can often be influenced by our emotions, desires, and personal experiences. In this dream, the romantic relationship between you and your close guy friend may represent a deep emotional connection and trust that you share in your real-life friendship. It could symbolize a strong bond or closeness that you both feel towards each other.
The feeling of betrayal in the dream may stem from your awareness of your friend's romantic feelings toward him. It indicates a concern about potentially hurting her or betraying her trust by pursuing a romantic relationship with someone she likes. This could reflect your own empathy and consideration for your friend's feelings, as well as your desire to maintain a platonic relationship.
Overall, this dream might be highlighting the importance of your friendships and the role they play in your life. It could also be a reflection of your subconscious thoughts and emotions regarding relationships and loyalty towards your friends.
