Yes but this is not a completely alien idea. We know that things that are moving through space with 100% of their movement through space (i.e., moving at the speed of light), 0% of their movement is through time.
Take a proton for example. From the proton’s perspective, its creation and destruction happen in the same instant. From our perspective, it may travel through space for some period of time between the two events.
We’re not completely sure about the nature of gravity, but given how gravity seems to interact with spacetime, it seems at least plausible that time outside the singularity compresses to a single instant from the perspective of someone inside the event horizon.
