Are dreams suppose to tell you something? Like the future?

I must really be getting up-tight about that note I gave Louis (well Molly gave it to him for me =]) because last night I dreamt about it, and it started off quite strangly. I was walking along this place, and I knew it was in Switzerland 'cause I used to live there. I was going to turn around the corner and expected to see exactly what should be there in real life, but instead I ended up ar my school. I wasn't sure weither school had started yet, I assumed that it was still the holidays but everyone was there, in their school uniforms, and I realized I was in mine too. I looked back and Bell street was behind me, and not the place in Switzerland, everything was normal. Well it turned out school had started apparently and I walked down and saw this group of 4th years, which were Louis and his friends. Well they saw me and I tried to hide my face, doesn't really work that well when you're the only person at the school with long black hair, and they recognised me. I tried to just walk past and ignore them, but then Louis called out my name and I looked around. "Look familiar?" he said as he threw a crunched up piece of paper to me. I caught it and opened it, it was the note I gave him, or so I thought. I realized that the words on the piece of paper was written in green, but the not I gave him was written in purple. So I opened it again and it said 'Yes'. I looked up at him and then turned round and started walking down towards the gates. He came and walked down with me and when we reached the gates he said that he did really like me but his parents won't let him go out with anyone (God I thought that was only my parents) he looked very upset. And then it went all strange and Molly was there, and I said "I thought you're suppose to be in France" "Ah well it got posponed to next month" weird and apparently in regi I was chewing gum, I hate chewing gum, why would I be doing that? Well then we were at the pillars and the some boys (mostly 4th years, including Louis) had to help with something. Me Kirsty and Chloe were just sitting there and as Louis walked past he ruffed up my hair and 2 of his friends did the same. I don't really like people doing that and then they came out again with the things they were suppose to be carriying, and they had no idea what they were suppose to do with it, quite funny. And then suddenly Molly was there again, and I asked the same thing and she replied with the same answer. It's cause I seemed to realize the 1st time was a dream and it hadn't actually happened but then this time it was a dream but I didn't think it was. It was really confuzing. Well that's basically what happened, imagine that really happened on the 1st day of school, omg that would just be, well impossible, and I'd probably faint or something (I've never ever fainted before, wonder what it feels like) oh well let's just hope that he is really as he is suppose to be. Being born on the year of the Dog, if he really was as it says people born on the year of the dog should be like then that'll be wonderful =], sort of.
