Grinding/screeching noise from the rear of E90?

My car started making this weird grinding/screeching noise from the rear right suspension. It is "metallic" noise, it almost seems like something is scraping a piece of metal.

It makes noise when,
-I go over a bump or uneven surface. Grinding noise occurs for a very quick second and goes away.
-Sometimes when I brake.

Some ideas were,
-Back plate (what the hell is this?)
-Suspension components (ex: bushings making noise, but I doubt it.)
-Brake parts (ex: rock is stuck somewhere, bent dust plate, etc)
-Rear right wheel

Can anyone give me some opinion on this? If you heard anything, or went through similar, please share.

I have no idea what it is, but I'd get it taken care of ASAP.

Grinding and screeching noises often turn into snapping and breaking noises.
