A phenomia which would move folk through timelines

[Derek Jackson]

Can anyone suggest some non human controlled phenominan which might somehow cause people to move, slide, from one time line to another?

Micro black holes. Billions of these were created at the Big Bang but most are thought to have evaporated within a few million years of the event. However, due to the Heisenberg Uncertainty Principle a limited number survive by slipping into other Universes, continuing on thru other timelines for eternity. The ones from other Universes, of course, also sometimes slip into and through our own.

They will catch and take with them any unfortunate thing or being that is close enough and pull it through other Universes with them, the person and the hole becoming more and more distant from each other as they pass through successive Universes until the one is finally left behind. These random events account for most of the Aubrey Beardsley events which baffle the modern world.

How about ghosts?

Standing in exactly the same spot as their alternate time line self when near to some quantum physics experiment?

Some stars might generate natural wormholes which constantly appear and disappear in the region surrounding them. These stars might be neutron stars, or "magnetars" which are stars with extremely powerful magnetic fields.
Exploding stars, or colliding neutron stars might generate such space warps.
