OK, "stories" are different from True fact, for all you know, and its more than possible that they all lied, although i do trust a few friends on it such as shadowed stranger and Ichigo, other story's don't make any scence
And where did you get true fact? No one can say: IT'S FALSE/TRUE! Without solid proof. We have no proof that the tales in Q&B are false/true.
The one thing I try to never do, is to dismiss a case as false. All I need to do is come up with another logical explanation. But if it's obviously fake, like a person is in the TD world or something, I will dismiss it as either a dream, a delusion, fake, or unneeded for the topic. If someone "visited" TD's world, it doesn't make him anymore real, as it can easily be dismissed as a possible dream/delusion.
