Rivers & whirlpools of spacetime

Do rivers (conduits) or whirlpools (sinks and sources) of spacetime exist, which deform as linear, spiral or chaotic flow, eventually accelerate superluminally relative to nearby spacetime?

...whose topology can deform in time and space like the above-mentioned "river" or "whirlpool." I asked whether sheared or chiral spacetime may develop singularities spontaneously from their displaced geometry.

Regarding "whirlpools" I would say, yes. I think that is exactly what frame-dragging is.

"Rivers" are a little more difficult to imagine a cause for, but I suppose that they might exist. As for accelerating superluminally, I highly doubt it.

Well, they say there's no actual limmit on the
"velocity" of space-time itself, so why not ?

Live long and prosper.
