In the yeeaarr twooo-thouuu-sannnd...
Item: Someone (bearing a plausible superficial resemblance to you) surprises you in your bedroom one night, in order to warn you of a terrible disaster that will befall if you follow a particular course in the near future.
Question 1: How do you determine whether this is "future you" or a clever and well-informed imposter? Be specific.
Question 2: Assuming that they are a "future you", by what process do you determine whether the advice they're giving you is good, or merely self-interested? (Assuming you're prepared to make a distinction, which can be tricky in the case of time travel scenarios.)
