When I turn my rear wheel my cassette wobbles and makes this weird noise...any of you know how can I fix this?

This is what I would do:
1.remove the wheel
2.make sure the cassette is secure to the hub. There should be a lockring that holds it secure. If there is not, or if it loose, then that is your problem!
If that isn't it....then take off the cassette (you will need a lockring adapter to do this) and inspect the hub.
hope this helps.

A bent axle could be the cause.
Maybe even a FreeHub (the part that holds the cassette) might be cross threaded. This happened to me once, but it was a free wheel and not a cassette.

I'm sorry for my unfirmiliarity but what do you mean by cross threaded?

Please don't take this as an insult or criticism, but the fact that you have to ask what cross-threading is suggests that you may not be ready to work on your bike yourself without some homework. Please get a book on bicycle mechanics. Bike mechanics is pretty simple if you have a good book.
Cross-threaded means the threads on the two mating parts were not properly aligned as the parts were screwed together, resulting in the threads crossing each other. Cross-threading often destroys the threads on one or both parts. Threaded parts should always go together pretty easily until the very end when it is time to snug them down. If after about one full turn the parts suddenly seem very hard to turn, they are probably cross-threaded. One should back all the way off and try again to properly align the threads until they screw together easily.

On older screw-on freewheels, there is often some wobble in the cogs . Im my experience, this is no big deal and had never caused me a problem.
When you attatch a freewheel, you screw a cheap steel part onto an expensive soft aluminium part. The steel can cut across the al threads and ruin them. You need to reverse the threads until they click into position then slowly screw them on. Its basic workshop practice for any threaded parts.
Modern cogs do not screw on, but slide along a ridged (splined) cyclinder. These should not wobble at all.
