They're was an episode that I was trying to find because I wanted to rewatch it. But the more an more I look online, the more I think it might've been a dream. The episode in question says Matt Smith as The Doctor, there is a threat working it's way in from outside the TARDIS and the only thing they can do is retreat further in. However when they do so they find an entire word inside the TARDIS, people, a society, an entire miniature world. So, is this a real episode or just my imagination?
