I don't know, Sammii, I think that dreams can be meaningful sometimes. (Not all the time though.)
For example, yesterday I had to say goodbye to the senior class; they're doing personal internships for the rest of the year instead of going to school. There's one senior who I knew I'd miss a lot. The night before they left, I had a dream about seeing him around school for the last time. Then he was in my dream last night as well; I dreamt that he was at school again on monday picking up something he left behind by accident.
