Dream About Friendship And Transformation

Had a dream in which I was invited to a party/gathering. Ralph was invited too. We arrived at the apartment where the gathering was held but no one was there initially. I got frustrated with Ralph for some reason to the point where I called off our relationship or friendship. I grew angrier with his reaction. It was as if he was okay because he wanted to talk to some one was and likely already was. Then Ralph transformed into Delvin. I was talking to Ralph but then Delvin appeared and I was talking to him. I was so angry that he was just non chalant about the friendship being over. Unsure why Ralph transformed into Delvin in the dream
