What causes this feeling the bright morning was full of threats and the circle began to change. It faced out rather than in and the spears of sharpened wood were like a fence. Lord of The flies?

This feeling of impending danger and shifting dynamics in "Lord of the Flies" is caused by the deterioration of society and the descent into savagery among the boys stranded on the island. The circle shifting outwards represents a loss of internal control and an embrace of violence and conflict. The spears symbolize the transformation of a once-civilized group into a tribe focused on power and dominance.
