The Time Anne Conjured a Ghost ( part 2) Why?

Previously :

                    Anne found a dream catch in a dark and peculiar cave. She took it home and when she hung it in her bedroom, she saw creepy eye in a corner.

Now :

          She was walking to school the next day, buried under her thoughts. She could not forget what happened last night. She somehow felt she was connected to those eyes. "Anne, come," shouted a voice from the distance bumping her out of her thoughts. It was her friend, Mary. After her friend ,Sara, moved countries she was left behind with no friends. Mary was the only one she found interesting in her class of 30 students. Although  Mary would speak only with silence and Anne could not survive a day without talking, they liked each other as a friend. Unable to forget what happened, she spilled her thoughts out to Mary.  Mary was scared and felt bad for Anne yet she did not believe most of it. While they where talking Anne saw those eyes again, behind Mary. The same feeling crept into her mind. Then they vanished just like they did last time. What was happening? Why was this happening? We will find out in our next part.
