A time loop? Like, you went total Groundhog Day? Did you take up the piano or ice sculpting? I mean, I guess the movie kind of makes those things cliche, but insanity seems like a surefire bet there.
A rift? Not that I know of. Probably not the best person for that kind of question, but there's no shortage of people here who are. As for the repeat visitor? I'm told this is trip number four, and I don't remember any of it either. Which is new, and weird, but the lack of imminent danger lands this one in a decidedly plus column.
