Some say that imagination is the mind remembering the future. You can also imagine a future place. In fact, there's really no way to imagine a future time without simultaneously imagining a future place. How would that work otherwise? Would you just imagine a future date? Like a number on a calendar? Well, that calendar has to exist somewhere. A date is really just the name of a date. An actual date is attached to a place, duration, actions, feelings, temperature, threats, pleasures... y'know: stuff.
