Alright, so I've been reading up on this "Slenderman" lately, and one thing always sticks out: the people he takes/kills are always terified of him. This got me thinking; if you're not afraid of him, can he hurt you? From what I've read (Tulpa effect, Quantom theory ect.) the answer seems to be no. I'm not speaking from experience, I've never seen Der Ritter, but I do know that I'm not even remotely afraid of him.
Please let me know what you think, and, if possible, your personal story.
