In my dream, A sexy liquid metal man had sex with me. His name is Busta. He and I were lovemaking. I had my pajamas on but his entire body was silver except his face. Busta would hold me while kissing me on my neck. When he morphed into a liquid, Busta would kiss me on my stomach. I really loved him and the sex. The dream ended when he told me that he love me, tickled and hugged me, gave me a kiss on the forehead, cheek, neck and lips when he was a watery figure of himself, and he morph into a silver liquid and left. This is what he looks like

Sounds like a variation of an "unknown lover" dream.  Here's a link to the dream dictionary definition of that symbol on this website: dreamdoctor.com/index.php?option=com_dre...ls&id=1214&Itemid=24

As for why he appeared as he did, it's likely a creative choice by your subconscious.  Water/liquid is a common symbol in dreams for emotions.

The more interesting question to ask yourself, once you understand the symbol, is what caused it.   

Good luck!
