the behavior of space inside a black hole.

Please help me with the following approach:

The solution for a non-spinning black hole, according to the literature, changes the time coordinate from imaginary time to the real radial coordinate of the black hole, when the event horizon is crossed.

That is, time which is ordinarily an imaginary coordinate in GR becomes a real coordinate within the event horizon. Moreover, it is said to be the radial coordinate, which is presumably zero at the singularity and increasing to some constant value at the event horizon. So far, is this correct? (Forgive me for just asking you questions rather than solving the problem myself- getting lazy in my old age)

If so, then time is decreasing as we approach the center of the singularity. Or is there some other measurement of time? This all seems so paradoxical that I think I'll stop here and wait until I hear from you.

Regards,

Richard
