Talking german in my sleep. is this common?

How can I stop my sleep talking/sleep walking?

• I talk in my sleep every night. Usually gibberish but sometimes it is pretty clear. And I just randomly broke the bobble head on the table next to me in my sleep once. Also the other say I remember waking up and just randomly ripping pieces of a poster off. Another night someone told me I just leaned over the bed and started to feel around while talking. Also I've had I couple times where I just yelled at my sister for no reason in my sleep! All these events happened when I was in bed, is that considered sleep walking? Even the one where I ripped a poster (I was still in bed)? Is what I'm doing dangerous? And can I prevent it?
