My friend has told me that she feels like she saw an entity like Slenderman or has been targeted by one.
NOW TO CLARIFY I did tell her that slender doesn't exist but that demonic entities like it are real and do share similarities.
My friend originally told me about her first encounter a year ago. She said that she had heard a ringing in her ears, dreamed of Slender, electronics started glitching, and she had seen it when no one else could.
This could be very easily explained as her imagination but shes really freaked out when she heard that I had symptoms of the "Slender Sickness". I have been having nosebleeds and major headaches.. so she got concerned and started to tell me to be careful and then she said about 2 weeks ago she was having the experiences come up again! But she said she saw something on a roof that was tall, black, and had no face.
I want to help her but I don't know what to do. I really am worried for her and I want to know if theres anything simple that she could do to ward off this thing in case it isn't her imagination!

useless note* I believe in tarot so I told her to do a yes/no tarot reading and she got the Emperor. It said that she had let the emotions get to her head so I did recommend for her to ignore this and live life normally for a few days then look back and see if she noticed anything unusual or has felt uncomfortable.

I'm probably going to get a lot of replies that say "Slender isn't real. Your friend is imagining it," or "Tell her to lay off on watching scary movies before bed," but to be honest I'm going to ignore you (I don't mean it as disrespect but I'm just looking for a method of keeping this thing away from her!)
