I have heard about people who said they were here before, and they are just the re incarnations of people. But then I would become confused about the logic and so many questions would arise in mind. How it is possible? The world population has been increasing and how does this comply with the reincarnation concept? And if it is true, why does that happen? What is the scientific proof behind it? Is it related to our genetics? Do you have any idea? What happens to the dead people? Is it true that people can talk with spirits using mediums? Is there any truth in any of these claims? Has anyone here seen a spirit or talked with it? Please share if you don’t mind
