In a dream everything is created by you and your mind. This means that everything is created in the way that you see it. If you think flowers are/should be beautiful. They will be. If you think a friend is annoying, they will be. Looking back at these aspects of your dreams can teach you endless amounts about how you see the world around you.[/b]
I pretty much agree with all of your points except this one. Just because, dream logic...is...quite illogical at times. Or, most of the time. So I wouldn't expect everything to be created in the way that you see it, and sometimes, nothing is! I might think that a flower is beautiful...but that won't stop it from turning into a 7 foot purple ape throwing his arms around and then quickly turns into my dog being swallowed by a tulip...
