Ralph, in Chapter 7, is starting to be concerned about the look of the boys. He notices the long hair and unkempt appearance of them all, and understands in some way that it means they are losing their civilization, their identity. This desire for civilization again is shown in his daydream. For the first time, he doesn't think abstractly about home and getting off the island, but actually visualizes it. He thinks about the cottage he lived in with his mother and father, about feeling safe and protected there, and about sleeping in his own bed. Even though Simon tells tries to reassure him:
"You'll get back where you came from."
Ralph isn't too sure. This will become clear later in the chapter when Ralph starts to understand the power of violence:
"Ralph...was fighting to get near....The desire to squeeze and hurt was over-mastering."
A part of him understands that the more he gives in to that desire, the more he will lose himself and all civilized world.
