Dreams are a way for your brain to process what has happened during the day as well as sort things out that are on your mind, so it's not strange that you are dreaming about a character you have seen a lot.
If this is about the Pokémon Anime, there is no need to post in Pokémon General for this :) I will close this thread now and redirect you to the
General Character Discussion thread over in that section instead, where you can talk about Dawn if you like. Or if you'd rather want to discuss the fact that you have been dreaming about pokémon anime characters, maybe you could try and make a thread for that there!
