This dream starts out finding myself in my best friend's house. When I start to look around I realize that I'm in someone else's body. I find a mirror and see the reflection of his wife looking back at me. I'm not sure how long I just stand there staring. I then think I need to leave before anyone comes home. 
I hear someone entering the room and see my best friend. He walks up to me and gives me a very passionate kiss. I find myself responding to it. When he breaks off the kiss he just stares at me for a long time. He then gently taps my forehead and asks what I'm doing in there. Before I can respond he kisses me again with even more passion. I find my knees growing weak and if I didn't have my arms around his neck I would have fallen. 
I try to say something but he interrupts me and says I'm a very beautiful woman and a much better kisser than his wife. He then tells me that if we make love, this is who I'll be from now on. Before I can answer he picks me up and carries me to the bedroom
This is where it ended and I am certainly confused with this

I'm working on a dream interpretation.
But I just want to verify. Are you girl or a guy?

Thanks

The dream could reflects a search for self-discovery, desire for emotional intimacy, hidden feelings, and exploration of relationships, gender, and sexuality. It suggests a fear of potential changes and calls for introspection or discussion with others for understanding and support.  The dream's scenario might indicate that you have unspoken feelings for your best friend or a wish for a romantic relationship with them. The dream could be prompting you to reflect on your friendship with your best friend and assess the level of emotional connection and trust between the two of you.
