i've had different dreams that take place at the same location. Or i've had dreams in my house, it doesn't look like my house in my dream, but i know it's my house. Dreaming and the whole two worlds type of thing, if that were the case, then what would you define as reality? something to think about. Maybe you'd prefer to sleep the rest of your life cuz you like that reality better. Then you'd start to think of death.
