But, would any black hole "come with" a universe embedded or is it a property of absorbing mass?

The extent of my knowledge of astrophysics and relativity are around the size of the next comma in this sentence, but wouldn’t a great deal of time pass “inside” such a black hole such that a “universe” could rise and fall in what would seem to us as just a few microseconds due to relativistic effects?

The blackhole universe would seem to move infinitely slow to us and our univers would flash by in an instant to them...

Black holes still have finite mass, and can be lighter than Earth.

Wouldn't it be the other way around, if anything? Things closer to a black hole experience time slower.
