Hi. So I have a story idea and my main plot device has something to do with time. I want it to be a more science fiction than fantasy so I was hoping someone could help me. The general idea is, a man falls asleep only to wake up 20 years in the future, in one night, he cannot remember the last 20 years, but he has aged and so has everyone else, it as if time jumped forward and he's in the future. Is there any way I can make this plot device work without obviously violating the laws of physics, so it is reasonable? I don't want to use the whole 'he was frozen' plot device, I want it to seem a bit magical, but yet be a bit logical. Is it possible to do that?
