There are people who believe in ghosts and there are people who don't. Some people don't believe the existence of the ghost because they think ghosts are nonsense creatures which made up by others. However, there are other people who believe in ghost. Some people believe in ghost because of the culture and some said they had seen the ghost with their one eyes, also there are super natural things which happened in daily life are hard to explain. Based on the personal experience, the super natural things which are hard to explain and the people who claim they have the ability to communicate and haunt the ghost, the existence of the ghost is real.
First of all, the culture in our country do believe that there are ghost exist after people died. We believed that after a person died, his spirit will left the body, if he didn't have any regret of his life then he will stay with the family for 49 days, to make sure the family is well and to accompany them get through the hard times, after that he will leave the world and go to reincarnation. But if the person had some regrets before he died, he couldn't leave until his wish completed by others or he worried about his family too much that he doesn't willing to go, then he will become a ghost to stay in the world. Based on my personal experience, my cousin and I were very close, we were in the same age and grew up together. He and I shared a lot of things, secrets and wonderful memories together. We had a very strong connection. But unfortunately, he passed away this year. During the time we were preparing his funeral, my cousin appeared in my dreams every day, I kept feel uncomfortable and got sick very seriously. My grandparents said that was my cousin's ghost, he worried about me so much that he accompanied me, but my body didn't used to the spirit thing so I felt weak. After his funeral, because of the sick and my weak body, I passed out.
