What metaphors are used in Small Change by Yehudit Hendel?

The scenes of Rutchen in jail mirror far more intensely the entrapment and the violation she has felt all her life. When she speaks of the rape, she can only describe the chain of events metaphorically. Instead of the attacker touching her, it is snakes clearly advancing on her on her body, slimy, hissing, closing in on her and climbing up her and coiling around her neck and crawling into her throat and filling her mouth and her throat and choking her inside her throat.
