The characters personality
Here is the answer that would best complete the given statement above. After killing Duncan, macbeth is so distraught that he is hearing voices saying he will never be able to sleep again. He is having hallucinations about it, <span> seeing floating daggers. Hope this is the answer that you are looking for.</span>
Is he bipolar he may be bipolar or going through his own personal problem or he may just be uninterested in the friendship and trying to distance himself but dont want to hurt your feelings i wouldnt force anything and if he continues this behavior you have either to options talk to him and tell him how u feel or just distance yourself away from him
