Any body falling into a black hole will get completely destroyed. There is no such thing as an absolutely rigid body; a "rigid body" is an approximation that may help with some calculations, and such an approximation is valid (i.e., it's a good approximation) under certain circumstances, but a body will certainly not remain rigid under the extreme circumstances of a black hole.
In the real world there's no such thing as a truly rigid body. You would need to provide more details about the exact conditions if you wanted to determine what would happen to a hypothetical perfectly rigid body under those circumstances.
Your body will feel stretched and your body will stretch harder and form into pieces, that is before you fall in the black hole.
No - should you fall into a black hole (which is very unlikely to happen), you would get ripped apart.
it may damage them and the working of a lot your internal systems due to their harmful effect to the body.
Basically, the same thing can happen as if something gets too close to the Sun, or to a planet: it can fall into the black hole (or Sun, or planet).
If you happen to fall into a body of water (or if someone throws you in) while you are asleep, then yes, you could wake up drowning. This doesn't happen very often.
spaghettification takes place with you ( the process by which an object and in this case you would be stretched and ripped apart by gravitational forces )
