Superstition

I don't religiously believe in superstitions because some of them in my own opinion are really weird... But this one, I have heard from my cousin. She said when you dream that you're dancing with someone, perhaps slow dance, that man/woman will be your future husband/wife. She said that in the dream it seems as if you knew the person, as if every details of him were so vivid. But then when you wake up you can't remember the face. She said all she could remember was the built of the body and he's skin color. The face was blank. It's either you already met him or not. In her case, she already met the man but she can't believe that it will come true becoz he's not her type. Maybe, it's true, maybe not.
