These pieces has been spelled for time travel in dreams, visions and OBE's. It will show you the past, present and future. It is fixed where you can't change the past but you can go back and learn a lesson if you wish, or see things that have gone on before. The box that comes with it is it's charger fed by the elements. You can go see someone now if you wish, or you can go into the future, keep in mind though, the future is hazy as it is determined by choices now.
