That is normally a judgement call... The Dream Journal section is not only to share dreams, but to keep a digital copy of your dreams. If you feel a dream is too graphic, I would advise you not to share it. If it was troubling, and you feel a need to post it, feel free, but try to word it in a way that is not offensive. And if it is sexual, try not to broadcast it.

As for violent dreams, I love them. Its basically the same. You can post them, but e nice about it.
