Can someone tell me what this dream means?

I keep having this dream where I'm at work, but I can't concentrate because one of my male co-workers is sitting in the corner masturbating. Whenever I look over he stares me in the eyes and whispers something in crazy backward speech. I try to touch him but I realize my arms are skeleton arms, and every time I approach him his face turns into the face of my deceased grandmother. I start bawling, and my skeleton hands start showing signs of stigmata. Suddenly an alien materializes and tells me it's not my fault, I can come back home now and Father didn't actually lose his legs in the war.

Anyways, my question is, the dream was in black and white and I heard that creative people dream in color. Does this mean I'm not creative? This is important because I like to tell people I'm creative.
