I think this test is quite frigthening (I will let see you why).

So I got :
You scored as Luna Lovegood. You're an extreme introvert and because of this, are also a deep thinker. You ponder things others would never dream of pondering and stand with your beliefs without backing down. You find it more valuable to daydream than to socialize, because there's so much more going on in your head than others'. Most people don't understand it, but you seem to prefer it that way.
Luna Lovegood 84%
Neville Longbottom 66%
Severus Snape 63%
Albus Dumbledore 56%
Remus Lupin 56%
Percy Weasley 50%
Sirius Black 47%
Harry Potter 44%
Hermione Granger 38%
Ron Weasley 38%
Oliver Wood 38%
Bellatrix Lestrange 34%
Draco Malfoy 28%
Lord Voldemort 25%
First surprised to have this character (not one I'm really fond of)... but the good side is that I'm really far away from the Dark Lord.
But when I see the description of Luna... I'm like... well maybe it's quite true...
