Consider that every "surface" inside the event horizon is like a stronger event horizon so passing through you'd certainly notice things like not being able to see your feet any more as the light wouldn't be able to travel out to your eyes! There would be a lot of other stuff happening too so you may not notice exactly, but the event horizon is definitely noticeable!

    The horizon is the distance at which escape velocity is c.

    Closer to the centre, including your feet, the escape velocity is higher.

    Electrical impulses wouldn’t be able to travel from the bottom of your brain to the top, so you’d be unconscious anyway.

      It is absolutely untrue that GR predicts that you would be knocked unconscious crossing the horizon. In fact one of the most fundamental aspects of GR (equivalence) predicts the exact opposite - there is no local experiment you can do as a freely falling observer to detect the horizon.
