What do you mean by dreaming that a ghost is killing you?
1, if your family are theists, instead of party member in * * *, then I tell you, if you believe this thing, you won't believe it. Since you are so worried, you'd better find a Feng Shui gentleman to see if there is anything wrong with the structure of your house. Generally dreaming of such dirty things, the house feng shui is definitely not good. In ancient times, we had the Book of Changes, which specializes in geomantic omen.
2. From a scientific point of view, this phenomenon of yours may be a nightmare, and there must be something wrong with your sleeping posture. When you sleep at night, be careful not to press your heart or sensory nerves with your arms or other objects, otherwise you will be particularly painful in your dreams. A person usually has 4-6 dreams at night. If your heart is pressed by your arm, you will be out of breath and feel uncomfortable in your dreams. So you should consider this aspect.
3, this is superstition, which has no scientific reason, but according to the old people, if you are haunted, it is because you have recently passed some ground-breaking places. As the old saying goes, places that break ground are generally strange, so if you pass by those places that break ground, such as construction sites and new graves, you must find a place where no one will give it to you at night. The ghost who died tragically burned some money, such as gold ingots. Be religious, tell them not to come to you again, give them money to buy clothes, but don't give them any promises, or they will still harass you if you break your promise.
