How would you describe what happened on the night that Macbeth murdered Duncan?

Macbeth stabbed King Duncan and his two royal guards to death. That night, Banquo and his son spoke about the lack of a moon and the presence of heavy wind [Act 2 Scene 1 Lines 2, 4-5]. The next morning, Ross and an Old Man also spoke of atypical weather and animal behavior. Specifically, Ross referred to the pitch blackness of the day [Act 2 Scene 4 Lines 5-10]. The Old Man, in turn, spoke of the unexpected killing of a facon by a mere mousing owl [Lines 10-12]. Then Ross brought up the weird happening of the King's horses suddenly turning wild and breaking loose from their stalls [Lines 16-18]. The Old Man concluded with the shocking news that the horses had eaten each other [Line 18].
