Annoying dream

You know those dreams where you're running away from someone or something, but it's like you're trying to run through quicksand? It's really frustrating, no matter how fast it feels like you're trying to go, it seems you're always way too slow and the chaser is inevitably going to catch up.
This morning I had a variation of that type of dream, and I remembered that I had had this dream before. This one is about needing to call 911 while I'm in danger. Something bad will happen, someone's coming after me and I've only got a couple seconds to try to make that call. Sometimes as soon as I have that thought, I realize the phone has been disconnected or the wires have been cut. Sometimes I have my cell phone but either the battery is dead or it has no signal. Then there are times when I do reach a phone that is working, but something always goes wrong while I'm dialing. It's only 3 numbers - how hard can it be? But somehow my fingers will not cooperate! Rrgghh!
So, back to this morning's dream. I sat up in bed after hearing someone rattling the front door. It was just him and me inside, and it was the middle of the night. Then I heard a key clicking inside the lock and the door being pushed open. Even in my dream, my heart was racing. I woke him up and told him someone was in our house. We groggily and defenselessly went into the living room. There were about 6 redneck scuzzy-looking people walking around like they owned the place. I didn't know if they were violent, or just ignorant, or both. One guy with a cocky attitude and lack of teeth looked up and said "who the hell are you?" to us. At that point I started yelling at him "What? Who the fuck are YOU? What the fuck are YOU doing here?" Then this big lady stepped in. "Where's the people who used to live here? Where's so and so?" and J told them calmly that it was our house now and they'd have to leave. The lady then told us that they had been taking care of the previous owner's dog and it had died, so they brought it back here to be blessed before burying it. (???) Then I saw that the lady was holding the dead dog under her coat! She was getting beligerent, like we had made this an inconvenience for her. She and her people would not leave. Then they accused us of this not being our house and what had happened with the people who lived here before? I said I was going to find the number of the guy who sold us the house and sneaked off to find my cellphone and call 911. Of course, every time I tried, different numbers came up. 714, 817, damn it I need 911! But as I've said, in my dreams it hardly ever works. Finally I think I had dialed correctly, but when they answered, this guy just said "yeah". "Is this 911?" I asked frantically. "Yeah" he said in a smirking tone. "Sounds like you've had a bad day." Ugghhh. "I need an officer to come to my house" I whispered "we've had a break-in." After a long silence, the guy on the phone said "alright... yeah, I'll send someone over, but it's probably going to be about 20 minutes." I hung up. I was afraid that the people in our living room were going to attack us and I didn't know what to do. At least we were able to hide while they ransacked our house. The police did arrive shortly, although they were confused and not that helpful. The rest was kind of a blur. What an annoying, frustrating dream!
