Please help. What did this dream of mine mean?

I'm 17, and this is a type of dream that's not been unusual for me for the past several years. This one has stuck with me quite strongly, though. I was myself, but a girl. I remember being at this massive, really luxurious hotel/casino/resort place with all of my family except for my dad to celebrate my birthday. We were going to get dinner at some upscale restaurant on the ground level of this building (which had like 50 or 60 floors and a glass ceiling) when someone told me they heard my dad was on his way. This frightened me for some reason and I turned around and rushed to an elevator. I went up about 20 floors and got out near this bar and some shops. My aunt was there and I talked to her for a few minutes when she told me my dad had gotten there. At this point I took off down this hallway with a bunch of nice hotel rooms down it. I went inside one of them and locked the door. I remember the lighting was kind of dim and I sat down and changed my shoes from heels to some kind of boots, then I got up and looked in this mirror that was above the desk in the room. I took a really long look at myself. I had long reddish black (my hair's naturally a reddish brown) hair with straight bangs and the rest kind of wavy. I also remember I was wearing a black and white strapless dress that came down about mid-thigh or so. I remember feeling happy for a minute and thinking that I looked fantastic. Then I heard my dad calling for me, and I didn't know where it was coming from. I left the room and took off down the hall, which had gotten much darker, and eventually found myself back in the main area of the resort building. I noticed it was night, and then I saw a couple of my cousins and my aunt talking to my dad. That's the last thing I remember before I woke up. Please help me out here. I think I might already know what this dream and many others I've had are trying to tell me, but I want the opinions of others too. Also, my dad and I are pretty close, so I don't get why I was running from him or afraid of him. Anyway, please tell me what you think and thank you!
