Arguing? I was trying to give an answer to your question <.<
Why would the DC fool you if your 100% sure they are frigments of imagination? Considering, of course, the post about scientific information, isn't that then just because your expecting them to? Just use your mind to stop that or either it will happen again until you find a way to fool yourself or the DC, however you want to see it. Anyway, its not that common to find the kind of DC.
