How can you recognize something you haven´t seen?

Sometimes when I watch a movie I recognize things. Some times you remember you have seen the movie before, but sometimes it´s the first time you see it. It has happened several times, and I´m sure it will happen several more times.
Like, I recognize things from Avatar. And when I saw it was the first time I saw it. I was supposed to see it at the movies with my sister, but we never did. I saw it with a friend, and there were some parts that felt a little familiar. And when I thought about the movie afterwards I recognized things. Like the end when Neytiri goes to Jack and find him on the floor and gives him oxygen. And they lay their hand on the other one´s cheek and say " I see you" I know I have seen that before, but it was the first time I saw the movie. But I really recognized it. I have seen it before. Somehow.
And I think I recognize some things from Prince of Persia. But the same there, it was the first time I saw the movie. I know some things were in the trailer, but the things I recognize that weren´t?
It so weird when you watch a movie and you recognize things, but you shouldn´t, cause you´ve never seen it before.
Can someone explain?

Prince of Persia

Last night me, my sister and our friend went to see Prince of Persia. I thought it was really good, and I`m definitely going to see it again. My sister is going to buy it when it´s available on DVD, so I´m sure we will watch it a couple of times or more.
I really liked Jake Gyllenhaal as Dastan. I think he did a really good job. And I liked his look, the hair, the clothes. He looked good. And I really liked the character, and I think it was nice to see Jake play a part like that. He was cool and confident.
I also liked Gemma Arteron who plays Tamina. I liked the character, and I think she did a good job.
I think it was impressive when they jumped between rooftops, or between rooftops or down from a building and through a window or something. And I can say that I would not like to try. It looked very cool, and "Dastan" was really good, but I would not like to try.
The movie was quite funny sometimes, like when they were in the Valley of Slaves, or what it was called, and Tamina said something to Dastan and he didn´t know what to say.
I liked the special effects, I think they did a very good job. When they turned back the time, I think that was very nicely done.
I really liked the movie and I want to see it again soon.
I´ve tried not to think about the movie that much, but of course I have thought about it. But if I think too much, I will find something that I recognize, and I think I do recognize some things, even if this was the first time I saw the movie. But it has happened before.

I´m going to Spain!

I was so happy last Thursday when i found out I´m going to Spain in August. It´s with some of the people I work with. Our boss gave it to some of us as a part of the Christmas present. I wasn´t going at first, since I´m only working when they need me and not permanently emplyed. There was only going to be the permanently emplyed who was going to go, but J called last Thursday asn said that I could too. A thank you for working quite a lot, that they can count on me. I say no to work very rarely.
I´ve only been to Norway and Finland before so I´m very excited. And I`m glad that there was no problem getting a few days off from my summer job. But they are nice to deal with, so I never thought there would be any problems.
Now I just need a passport :)
