I would say this isn't quite right. It's true that time passes more slowly for your feet than your head, but this is due to tidal forces: your head and feet are different distances away from the black hole. For very large black holes, the tidal forces at the event horizon will be small, and the event horizon is the unexceptional, smooth spacetime that Steuard described. So in your example, for a large black hole, you will experience no difference in the rate of tingling as you cross the event horizon. This is what the principle of relativity tells us: you are in free fall, so the laws of physics must appear the same to you.
