In Lord of the Flies why does Simon frequent the bower?

I think that there is evidence in the book that Simon suffers from epliepsy. Simon often faints and he is also a bit of a loner, who likes to think. I think that it is important for Simon to have a 'secret place' of his own where he can go if he feels the onset of an epileptic attack. After witnessing the total lack of any support or care for Percival Wemys Madison, when the littlun spent two days alone in a hut crying and talking to himself, Simon would rightly fear what might happen to himself if the likes of Roger came upon him while he having a fit.
