trying to figure out what a ghost is , We have to find what we are first we are 3 dimensions ourselves. We are the past, present and future we have to interact with them at the same time.All thought is based on the past in order to interact with the present and the future. Science looks at the human as a chemical substance with reaction not as a electrical energy.So what is a ghost it is what it is there really isn't any logic, That's why I find it fascinating
