Confusing Dream while Napping! Help!

i was just taking a nap and woke up remembering the most confusing dream I've ever had.
I had a dream that my brother, my boyfriend, my friends and I were all at my house on a late night. We were all outside my house in the front and we saw a bunch of people who looked like scientists inspecting our house and getting samples of the brick, etc. I was completely lost. This woman came up to me and asked me what I was doing there, I told her that this was my house and what were they doing to my house and why were they here? All she told me was that it wouldn't be my house for long. Immediately I was confused again.

I woke up from t his dream feeling like I'd been having these dreams before.
My brother would get a call on his cell phone in my dream, and some person on the line would make him complete a task in order to save my life. The task would be dangerous and there was a time limit. The woman proceeded to shoot me in my left knee right before my brother got the call. I fell backwards and was immediately in pain. I went inside and my boyfriend was helping me. I heard my brother get the phone call with his task and he put his phone on speakerphone so we could hear the voice.
I closed my eyes in my dream and realized I was familiar with the voice and it was my dads voice.
My brother had to complete the task which I'm unaware of what it was, I just know it had to do with a bridge and an abandoned apartment.

Well....it's...a dream....^_^'
