How would we feel, if we are traveling  behind the event horizon?

Here, in the beginning, I must say, that because we cannot get any observations behind the event horizon everything, what we are writing is actually a fiction, because we don't have observations from the other side. No material object and even light can escape from the black hole. Or in theory, those particles, what are pulling in the black hole might come out from the white hole, but there is no evidence about the existence of those things. Or maybe white holes are existing in some other universe or distance.

If we would drop behind the event horizon, what would we feel in that case? The reality is in the point, where the particle is reaching the speed of the light, the time will stop. And this extreme phenomenon has been brought in the mind of the researchers that would we just see that the particle would stay on that point forever? Or would it just stop on the event horizon, and suddenly disappear after the stopping? When we would pass that point, we would be in the space, what is different than our own. But how different it actually is? Would there be actually nothing? Or would there nothing, where creature or natural forces may have an effect?

Is it possible, that material travels in a black hole or behind the event horizon so fast, that nothing can influence them? Or can the creature ever touch the core of the black hole? When we are thinking that the dropping would continue to the center of a singularity, we must actually notice, that the time is also be stopped, or goes backward. Or is there the time, as we know that thing? Or is the crushing gravity caused, that the time does not exist anymore?

Or how we would feel that thing? Would that means, that we will return to the point, where the journey began? If the dropping continues behind the event horizon, would the particle travels by hyperbolic trajectory and come out from the black hole from its poles? So could that thing duplicate that information? Or if we would travel inside the black hole, would the time deny that we would ever get older, or would we just sit and wait for the end of the black hole.
