[EX Q]: I have watched 6 seasons of Supernatural, and in almost every one of them, Sam and Dean talks about many different kinds of monsters- with different names, killing-methods and habits. So I was wondering, is there any credibility to that information? I mean, monsters are not considered real by most people (and most probably they aren't), but I do know there are many myths and legends about them- originating from ancient times. For example, in Supernatural, they almost always use salt to keep monsters away, and also the much-used Devil's Trap. So is this kind of lore real or just made up for the movie?

[EX Q]: In Game of Thrones Season 5, we see that the wildlings killed by Wights revive as Wights themselves. Jon Snow, Lord Commander of the Night's Watch, gets hurt while battling the wights and one of the White Walkers. Later, he gets stabbed by his brothers in the Watch. As he got hurt by the Wights and the Walker, does that mean he would revive as a Wight himself? Or is it such that those who get killed at the hands of a Wight only will revive as a Wight?

[EX Q]: In Single Man (2009), Kenny & George remove their clothes & go swimming at the beach after having drinks at bar. After the swimming is over Kenny tells George he'd like to visit his home, so George agrees & Kenny goes to his house whilst naked. So George asked him like this: George: Are you out of your mind? Kenny: What's the matter? George: You can't go home like that. Kenny: We're invisible. Don't you know that? I didn't understand the use of "invisible" in this scene context, what makes them invisible?
