Well this is one most fascinating questions in astrophysics, but unlike fascination, scientist have tried to answer this fascinating question not based on fantasy, but on the basis of scientific data available on the black holes, and general relativity.
Let’s go back in 1905, year known as year of miracles when genius physicist Albert Einstein proposed his theory of relativity and special relativity, which relatively blew all his contemporary scientific minds, which revolutionized the physics and was the basis of introduction and understanding of black holes. According to the theory of special relativity, the space is made up of space-time fabric. Every object which settles on this space-time fabric bulges it a little inwards, like a ball settled in the center of a trampoline. If you drop another ball from any point on the perimeter of the trampoline, ball sinks in revolving around on the trampoline and bulging in every point it goes over.
Now suppose the object is Sun which is settled on space-time fabric. Planets including earth are balls are suspended, and revolving around. But they don’t sink down. Why??? Because there is a constraint that don’t let happen it and called ‘schwezerald’ radius. This is the radius of bulge created by the object settled on space-time fabric. When crossed, that object converts into black hole.
Anything, including light would sink in if approached in the vicinity of the black hole. As they are of mass millions to billion times that of the sun, curvature of bulge made by them becomes asymptotic, and converges in to a point called singularity.
If you mistakenly fall in the black hole which is highly unlikely, you won’t have time to notice what’s happening around or if a little time you have,you will see things falling in to the black hole ,which would have already fallen in to the gravitational giant, time would be dilating there. You will split in to atoms, and sink in to the black hole, like toothpaste squeezed out of its packet. You will convert in to energy, again allowed by relativity. What happens after reaching singularity? Allowed by quantum mechanics, there is anti particle to every particle. So may be after singularity you may reach another universe, or say an anti-universe. May be you meet an ‘anti you’. A person of opposite nature of yours and opposite in every aspect and here once again allowed by quantum physics, you will annihilate with your anti you.
So it would be more placating to think that I never meet a black hole.
