Just a Thought

I was just pondering the mention of circling vegetables by the ghosts that haunt Hugh and play with his dreams. I think these ghosts may be his own memories. Anyways on page 553 the ghost narrators say (I coould quote the whole page, but will not):
"Human life can be compared to a person dancing in a variety of forms around his own self: thus the vegetables of our first picture book encircled a boy in his dream--green cucumber, blue eggplant, red beet, Potatao pere, Potato fils, a girly asparagus, and, oh, many more, their spinning ronde going faster and faster and gradually forming a tarnsparent ring of banded colors around a dead person or planet."

i picture a person's memories spinning like a halo around their head, like remembered salvation. Dancing in a variety of forms around oneself, like always trying to find ourselves, or something? Or different years of a person's life?
