I have a ghost on me. He can talk with my mouth. Sometimes I can't walk, but I can walk very fast myself. I know it's a ghost

Look at what your religious belief is, such as Buddhism. Find a well-protected temple and ask the master to help you solve it. It's best to switch to three places. Believe in Buddhism, accumulate virtues and do good deeds, and return the merits to all beings in your body. Because this is the predestined love between you. So handle it properly. As soon as possible.
