Is it possible that anxiety about the 11+ result could be being projected onto this particular bogeyman? It affects different people in different ways. My DS had a dreadful start to Y6, running into all sorts of problems at school, losing stuff, developing all manner of minor ailments, etc. He claimed not to be worried about the 11+ and indeed appeared quite relaxed about it, but as soon as it was all done and dusted (and we had to wait much longer then) the problems seemed to disappear as if by magic!
Fingers crossed next week.
Yes it had occurred to me that the bogey man could be 11 plus anxiety. However there are a couple of other children in her class that are also very frightened. It is a character called Jeff the killer. I researched it and it is really scary. It is a stour about a man who cuts a smile out of his face, hides in wardrobes, whispers go to sleep to children and then kills them. Upon deeper research I found that this characters picture was morphed on Photoshop by some sad person from a picture of a poor shall we say larger child who had posted a picture of herself and then been cyber bullied into committing suicide. The bullying went on even after her death with people continuing to post very nasty and inappropriate things. It has become a competition of sorts on a site called creepypasta to see who can come up with the worst story about how the Jeff the killer character came about.
My DD knows the full story now, her imagination was worse than the reality, she was slightly better last night. The school are taking it very seriously, as they agree that it is not appropriate for children of this age to be accessing such stuff. They are going to send a message out to parents to warn them to put parental controls on their computers. It has given me the kick up the backside that I needed to put very stringent parental controls on my computers and Ipad and phone. I would suggest that you all do the same, there is some really nasty stuff out there.
