Can you include the author???
A Constrain is something that imposes a limit or it means to prevent something from occurring.
Example of a sentence: We had to terminate the project due to time constraints.
During the play, there are several visions and hallucinations that are suffered by the title character.
The first hallucination is the bloody dagger which Macbeth sees right before he kills Duncan, symbolizing the bloody path that he and Lady Macbeth are about to take.
When he sees Bangho's ghost he is being reminded that he has murdered his friend.
Then, Lady Macbeth begins to sleepwalk and hallucinate, seeing her hand full of blood that she can't wash away.
These hallucinations symbolize the guilt that they feel over the growing number of deaths that he and Lady Macbeth cause in order to stay in power.
What does this mean? whats your question?
