How much did Du know about the Supernatural before Du started watching Supernatural?

Nothing.

Some things

Quite a lot, actually. I'm a bit of a geek when it comes to Supernatural and creepy stuff.

I have one in 2009 I went to see both MBV and friday the 13th remake and the guys was in those Filme that was cool. I was all way say oh wow the dude from gilmore girls and the dude from Smallville is doing a Zeigen together thats awesome but I did not see the Zeigen all the way just parts untell 09 win I rented the 1st season on dvd and seen all the eps on that. I did not get so much into that Zeigen untell last summer I seen the Season F of season5 and was saying to myself WTF? thats win i got into the wshow.

about the things that go bumping in the graveyard? nothing i might got killed easily on the Zeigen XD XD

i knew about ghosts,bloody Marie,Shapeshifters..etc
well i always been interested in this kind of stuff
so i know a lot because i do some research and my mom always told me when i was young about legends and stuff like that
