Strange vacation?

I was on vacation with family and friends- people I don't know here, and things felt a bit weird. The brother and I were being singled out by our mother figure as if she didn't like us a whole lot. I really didn't care, but the brother kind of did and I didn't want him feeling upset. This is where it gets fuzzy. At some point I find myself walking through someone's room to a back porch and go out. I stand out there just staring into this really amazing looking woods and I look down. I see the person who felt like a best friend walking into the woods rather quickly. The next thing I know, I'm down there as well, following her. I hear the sounds of my brother and his friends coming after us. The friends doesn't care, she's really excited. We eventually come upon a nice house in the woods with a really pretty front door. My friend stops and stands there and starts drawing. She keeps saying "I've found it! I've found it!" As I watch her draw I notice it is a picture that I've seen hundreds of times before from when we were younger. She had always known she was adopted, but she remembered this house. The next thing I know, she enters the house. I follow after telling her we shouldn't be here. We get to the second floor, walking around this big open hall way, and one of the room doors opens. A woman steps out and when she looks up she saw the friend. She told her you shouldn't be here. We both left the house, but the friend is still smiling like crazy. She falls back against the door hard and starts laughing still saying "I've found it. I've found it. After all these years I've found it." She then goes on to dig through her pockets for something, not caring if she pulled out wrong papers. She gets up and starts walking back towards my brother and his friends still grinning. I pick up the other folded bits of paper she left and followed after. One of the brother's friends asked me why I take care of her like that. I don't think I answered because I was watching these glider squirrels that were following us. By the time I looked at him he was up on a hill that we had come down. someone had to.
