You probably do not want to go very near a black hole, but if you are so curious that you need to make a trip down there, here is what will happen. After all, black holes are without question some of the strangest places in the universe.
What happens to your body as you fall into a black hole isn't pretty. A tidal force is a difference in the gravitational force between two points. The most familiar example is the tides we observe each day, especially at ocean fronts. The gravitational field of the moon causes the Earth to deform, as the strength of the gravity is stronger on the s near ide of the Earth that is facing the moon than the far side. The liquid ocean gets stretched even more and we observe larger tides.
This same tidal force applies to your body when you are falling into a black hole. The difference in acceleration between the head and feet could be many thousands of Earth gravities, and you will literally be ripped apart. Physicists call this phenomenon "spaghettification"!
