RIFT EARTH

Throughout history and even now, there have been and will be accounts and sightings of out-of-place people, men walking through New York City in a colonial outfit, or an old French knight walking through a small town in rural Nebraska. 

The reasons for these sightings are mostly unknown and have simply been thought to have been just regular people, yet others claim there are rips in time allowing people to travel through time or accidentally skip forward or backward in time, these rips are often called "rifts".
