Vacation weird

So this was a weird two parter that took place in the same location. My family and I were at this huge summer home and we were packing up from a long week there. What struck me as strange was all the stuff that they were leaving. Something like a black purse, which I was looking at my sister because she had been complaining that she had nothing to put her yarn stuff in and she's been borrowing anything of mine. I went from room to room and I heard my mom talking to my dad about the other things that were here. I'm not sure if he was paying any attention since all he wanted to do was leave. It was strange knowing that I was trying to pick up things to pack them up when I would find even more of my sisters stuff. Like random piles of clothing! I knew my baby sister had been going through her stuff trying to get rid of a lot, but it kept seeming to accumulate and there was always more. I think I was trying to figure out why there was stuff that my family was leaving and supposedly there was going to be stuff they were taking. I ended up in a bathroom at some point and then suddenly the family was gone, but a group of friends was there. I have no idea why until it started hitting dusk and they started acting strange. There were about six of us and they guys were talking about strange things. At one point one of them went to another side of the house. We waited and waited, and then things go eerie. The others started to worry and debating on whether or not to track this person down. But everyone was on edge! It was like going on a witch hunt for something we had yet to see and they were already muttering about vampires. I know I panicked a bit too when the actual "vampire" showed up because somehow the group got splintered and one other girl and I were trying to find places to hide before making our escape. The thing was that there was actual terror involved. We ducked and scooted around piles of junk that didn't make good hiding places, but I think we got found at some point, like the vampire was only playing with us. I don't really know what happened to the rest of the group because after I got "caught" I got "bitten" which more or less was a kiss on the neck and not some blood exchange that they were so afraid of. And while I was trying to figure out where everyone else was, I just started waking up because my damned dog decided to bark at the neighborhood kids going to school.
