Please don't worry. Dreams are different from reality. From the perspective of scientific dream interpretation: when people are in a state of anxiety and trouble, such as in a hotel run by a friend, the floor is too noisy, which leads to your bad mood. Subconsciously, you want to change this situation, so when you dream of ghosts, you start to find ways to solve it, such as chanting Buddha's name and writing ten thousand words. The so-called ghost symbolizes noisy sound. You hate and fear that sound just as you hate and fear ghosts. This is to analyze your problem from the perspective of scientific dream interpretation. In order to further elaborate this situation, I would like to add the following points.
Although dreams are the manifestation of people's subconscious. In fact, people's subconscious is constantly changing, hehe. This is very important. For example, you liked someone very much last year, and even dreamed of him at night, dreaming that he took the initiative to date you. You don't like him this year, and even hate him. So, when you dream, you may dream that he left you, hehe. When you understand that the subconscious mind is constantly changing, all you can do is live in the present and relax!
