My mom is playing cds on the stereo and she's raised the volume to an extremely very high level. It's so loud that the floorboards of the second floor is shaking. I mean, I'm sitting on top of my bed right now and *it* is even also vibrating! Isn't that bad? I'm not very good in Physics but I think we discussed something like this in class before.

Looks like a case of resonance. Some of the vibrations are matching in frequency with the walls and the floor of the house.

Everything has a special frequency related to its own called fundamental frequency. At this frequency, the body vibrates to a very large extent to even waves of relatively small intensity. This is called resonance.
The CD playing the music must have had the frequency of your floorboards. So they vibrated. Play a different CD at the same volume (some different sort of music). You will notice that the floorboards do not move any more. That's how opera singers break glasses with their voices. The trick is to get the same frequency.
You can change the fundamental frequency of a thing by changing its orientation.
