Go Ask Alice - Symbolism

In Go Ask Alice the symbols I can understand so far are the worms and maggots in her dreams. These disgusting insects are munching on her body. Alice feels scared and fears these dreams. These bugs could be representing the drugs shes taking. Drugs do rot your mind, your health and your social life. Besides the drugs it can be a representation of the nasty peers in her school. They despise Alice and mess with her. Dreams are known to be brain's way to catch up on things you forget or repressed. On the good note I had a pleasure dream last night and I account that on not thinking about $&* that day!
