Thomnas-

It sounds like something is loose inside. When it moves, it changes the water flow.

I suggest you remove the aerator and see if there are any small stones or bits of trash behind it. Worst case: if an aerator is clogged with lime deposits, soaking in vinegar might help dissolve the lime.
