Is it a disaster for people to sleep under the beams? What's wrong with it?

In fact, you don't believe that there is nothing. If you believe it, that person can't sleep under the beam, and it won't be a disaster, but it will be bad for people! People who sleep on the beam will be split in half by the beam, which is a taboo in feng shui, and people will be unlucky! Gas flows indoors, but when it meets the beam, people are bitter and depressed!
