Must... interpret

Kay this is a dreamI had an hour ago (By my time) and I found this one very vivid... Mostly due to the fact that I woke up in the middle:

A little backstory
I fell asleep after waking up and talking to my bro who was going to play in the band. I don't really like my bro and he annoys me a LOT.

the dream:
I found myself sleeping, got up and went to my comp. My bro was on my comp and I shouted at him to get off. He said no so I pushed him. I saw that instead of our normal dektop monitor he was using this enourmous one. There were like three open desktops siting next to this gigantic monitor. Also he was on one of my discarded AIM accounts. He got a call on his cell phone and I snatch the phone from him. It says Mope.. I disconnect the call and tell him who was calling. He says ok... Then I'm back to being mad at him for being on my comp. I notice that he's using a completely different computer than the one that I use... ( Which is a really crappy computer that I share with my parents because mine broke down). I shout at him to get off and he says ok and leaves but before he does he's says "It's mine".
I follow him and say "So I get the crappy computer and you get this great one?(He's got multiple computers, some are pretty good but he dumpster-dived for all of them, and I subconsiously knew that that was how he got this one). He takes his computer which is 3 times as long as it is tall or wide. and goes. Suddenly I realize that he's on my old AIM account so I go into the garage where he uses his computer and I ask " Why are you using my AIM account?" He replies "I can go anywhere with it" and smiles. I shout at him to get off my account then punch him ( he's invulnerable) He says "It's mine" I run back inside and lock the door so he can't come inside (he hates that and always gets mad when it's done purposely or accidentally). He notices and starts banging on the door, I see that it's starting to bend in the middle and a crack forms which I can see him through (right in the center) I run back to my computer which is now suddenly plugged in and the first thing I do is turn it on to go to dreamviews, after I hit the power button I look for a weapon. He breaks down the door while I'm looking for a weapon and before he even gets past the door (after breaking it down I don't know why I knew that he wasn't past the door yet or that he broke it down because I coudn't see the door. Then I woke up in a sweat.

I need help interpreting it and if there are any inconsistencies I'll be happy to clarify.

This is my first interpretation post.. I think but it just freaked me out so I hope someone can explain this to me. :)
