Scary dream

So, going to bed late isn't enough, I have to wake up half way through my close-to-nothing hours of sleep with a scary dream.
It was a confusing dream to start with. It was all one building - the school, my house, the mall, a dining lounge of a hotel with a swimming pool downstairs... And it seemed like the place was haunted. It had an aura like the one of that Tower of Terror ride from Disney Holywood Studios. First I was scolding some students for getting themselves in trouble. Next I was in this dinding lounge. For a minute there it seamed like I was in a train's dining lounge. Well, since it was haunted, there were monsters and ghosts around. By the end of the day, I was at home with my husband in the computer. Then we heard steps coming into the computer room. It felt normal. When it's night time, people are supposed to be arriving in the house. And, in our house, when someone arrives they walk into the room where there are other people. What didn't occurr to my dreaming mind was that , the only person that should be arriving in my house and walking into my computer room should be my husband. My husband, however, was sitting right at the computer with me. So we heard the steps and waited for a familiar face to show up at the door as if it were the most common thing in the world that someone else arrived at our house. Dad walked in and looked at us. No, the fact that dad passed away last year did not freak me out. It is common for children to be home and dad to arrive from work at night. That was all I had in my mind.
But here's when I freaked out:
"hi, dad," I smiled.
No answer. Just a blank stare. That was when it occurred to me, maybe dad was a zombie. He just stared.
"dad, for real, you're freaking me out. It seems like you're a zombie. ... Dad, just say something. .... ... D-Dad, quit the blank stare and say something. You're really scaring me. ... Dad? ... Oh my gosh! Oh my gosh!" That's when I realized he was some sort of zombie and that we had no place to run, considering we were on the second floor and the only thing dad wasn't blocking was a window. That's when I heard Dean's voice, "Sweetie,wake up! You're having a scary dream."
I had woken him up with my heavy breathing, and it was still a while before I was able to calm down.
And then he wonders why I freak out when he does zombie sounds!
