The dagger Macbeth sees is a hallucination. Becuase Lady Macbeth has put the idea of killing King Duncan into his head, Macbeth is beginning to wonder what to do. He believes he is seeing a dagger and believes that it is a sign for what he should do.
It is possible to suggest a number of answers to this. Some might see in the dagger a symbol of ambition, leading Macbeth toward Duncan, and being incapable of being grasped in the same way that it is impossible to satisfy insatiable ambition. Others might see it as a warning of the mental instability and hallucinations which can result from murder, and which do affect Macbeth when he sees the ghost of Banquo and his wife when she sleepwalks. It may be considered a foreshadowing of Banquo's ghost. It can be considered a symbol of guilt, particularly when the blood appears on it.
