Is it normal a dream or is there some meaning?

I had a crazy dream. I dreamt that I was going to my grandmothers house riding an orange dirt bike. when I got to the back of her house there were three tall fences keeping me from going any further so I dropped the dirt bike and climbed all three fences. I knocked on her door but there was no one home so I turned around to leave and now there was only one tall fence and a bunch of small 12 foot by 12 foot fenced in areas with four foot fences. There was a hipster type white guy (strange because my grandmother lives in the hood) with his big brown dog who had folded up my bike and was wearing it like a backpack. He was starting to leave so I yelled at him to stop with my bike and he says "park it" with a defiant douchebag look. I don't know what that means so I start climbing over the fences to get to him and tear him up, but then he throws a sport bike tire into the area next to him and where there is a very angry wild pig with jet black fur jumping around. Then suddenly it's in the same area with me but now it has like a elongated mouth with pointy teeth, like a baboon. I started to back away but there was a big black dog behind me that was growling. Then they both attacked at the same time. I tried to climb out of the area but they kept biting my legs when I tried to climb over the fence. I got frustrated and extremely angry and decided I would kill both of these animals, the hipster, and his dog or die trying. So I rushed the pig thing and grabbed it's upper and lower mouth and started to pull them apart in an attempt to rip it's jaw. So I'm slowly spreading it's jaws wider and wider and I'm waiting to feel and hear the snap but it never happens. It just keeps getting wider until it's almost completely backwards like it's jaw is made of rubber or something. I was thinking why the hell won't this things jaw break and the the other dog who had been there barking a growling attacked and locked onto my hand. I did not let go of the pig thing and decided I needed to break it's neck somehow. I looked over at the hipster and he was just petting his dog and singing a song. I got so angry that it woke me up. I feel like this dream has some meaning, but I don't know what it is.
