I never remember my dreams because they are too fast to catch them and see what they are all about. I'm not really sure if its possible to dream long stories and then not to forget them like i always do. Maybe it's because of a good subject to conversations what dreams are. When you've just asked about the weather and the answer is not as good as you expected you can say 'oh i had such a strange dream...' and so on.
Don't you think its true?
