describe how gregor physical characteristics become insect like, describe how his his inner self becomes less human as the metamorphosis progresses.

Gregor has great difficulty in getting out of bed and opening the door, but constantly excuses this, saying that he is drowsy, that sometimes one wakes up with aches and pains that turn out to be nothing upon getting up, and that he feels a slight indisposition. We get also the impression that Gregor is already alienated from his own body, since the sudden change does not inspire any strong feeling in him. It is as if he has switched from one foreign body to another, less convenient, one. Thus Gregor's strange alienation from his body is given concrete form in his metamorphosis, as he calmly explores his new form. He coolly observes that he cannot control his legs, that he lacks a clear image of the lower part of his body, that he does not know why places on his body itch or what those places are, and he observes, with almost clinical detachment, that he must be damaging his jaw in turning the key since a brown fluid is pouring out. He overestimates the hardness of his back and he experiences aches in unusual places, but none of this really surprises him. Gregor examines his new body as another vessel, just a new shell he has been placed in. It seems almost as if he had never established any identification between his self and his human body, so that a change of form is no big surprise.
