The strangest Dream? any insights please....

Last night I had the strangest dream (no, not the intro line to "nothing going to break my stride"). I was some law agent in either Hong Kong or Tokyo, I'm not sure. There was a petite asian woman there too. I was investigating some crime ring that was dealing in cosemetics. So in this dream I'm inspecting these various types of cosemetics: fingernail polish, lipstick, moisturizing cream, etc... So I end up rubbing this certian lotion all over me. For some reason I'm wearing a tank-top. I go to the bathroom and my arms, face, hands, shoulders, everything, is blue. Like the blue face paint used in Braveheart during the battle of Sterling.
So, thats the dream, but not the weird part. I wake up this morning and I have blue residue all over my fingertips!!! K, I've searched all day and there is nothing in my house that could do this. Nothing in my bed I could have grabbed to turn them blue. Nothing I was handling last night could have done this. the residue was the same color as in my dream. It looked like when you play with fingerpaints, then wash your hands, and there is still paint in between the lines in your fingertips. It stayed there through my shower and up until around 2pm. It slowly faded away during the day.
Anyone out there have any ideas?
