Dear Uncle Dixer: My bed is facing my closet. Is this bad Feng Shui? Is it similar to the idea of coffin position?    

Answer: Not at all! Where did you hear or read this rubbish about facing a closet is like facing a coffin?

The coffin position only applies to the bedroom door and not the closet. Even so, the coffin position is not always bad depending on distance and other factors. So it is absolutely fine when your bed faces your closet.
