If you fall into a black hole, you can do no experiment to detect the horizon, it’s a completely unremarkable region of space to you.
The stretching is just because of tidal forces, which means that gravity gets so much stronger closer to the black hole that your feet are pulled harder than your head, you experience the same thing standing on earth, it’s just that the change in gravity is basically negligible here.
No, that’s not the case at all.
