Feng Shui: Can the ceiling of the bedroom be decorated in the sky?

No, sleeping in the sky is sleeping in the wild. There is an old saying that eating has a phase, standing has a phase, and sleeping has a phase. Do everything in a proper way. Eat standing and lying down, but you just don't eat in the bedroom, which is bad for digestion. Others still think you are a freak and don't speak the language. When you do it in an environment where you shouldn't do it, it's unnatural. In the wild of astronomical phenomena, you don't give yourself a good rest environment in Feng Shui. Moreover, people who sleep in the sky are generally beggars. So it's best not to.
