you were a proxy - slenderman mainly took interest in you because of your power to manipulate with light.you sometimes used it for casual things,like when you were walking out in the forest in the dark,so you just created a little bit of light for yourself.due to that,moths flew around you a lot of the time. however - you also noticed a guy,who the moths were always around,was also around you all the time.you assumed he was a zombie,due to the fact that he was rotting - and it creeped you out... this evening,you were sitting on a bench in the garden as usual,and you saw a moth flying around you - he was staring.again.
