There's a good episode of PBS Spacetime about Penrose diagrams: https://www.youtube.com/watch?v=T4oYvSH6jJ8

It gets a little far into the weeds in a very "the map is not the territory" kind of way, but is fun none the less.

I think (it is not addressed to my satisfaction in the video) that it is implied that from inside the black hole, assuming it was formed from a collapsing star, you would see all around you the event horizon: behind you, the unverise at the time you crossed the event horizin, in front of you, the surface of the star at the moment of its collapse. The singularity, as the post covers, exists only in your future, so you could not see it, even though you will always end up there.
