No, the chances are that you'll get mired in confirmation bias and lead yourself down an endless road of wild interpretation trying to verify things that aren't verifiable.

To put it another way, if someone told me that Slenderman was "classified as a 'Dark Faerie' from Fae" (as you just have), I would want to know who said it, when they said it, why they said it, the last thing they ate and the prevailing wind. If you can't obtain proof that something exists unless you already believe in it, how do you ever know when you're mistaken?
