When Coraline goes through the door, she enters back into her house – but everything is slightly different.
Coraline finds her “Other Mother” who is warmer, more attentive and a better cook than her real mother. Also, she has buttons instead of eyes. The symbolism of buttons instead of eyes is extremely important in this movie: it illustrates that the characters in the alternate world are puppets fabricated by the handler. It is later revealed that the Other Mother is the handler in disguise.
