" I feel that you should watch where you're going, stop being so loud and so verbally abusive to me".
Homeostasis describes an equilibrium that has been achieved in a specific system. Under the assumption that the water was relatively calm beforehand, the sudden storm disrupts the specific system sending it out of equilibrium, with perhaps violent interactions above and below the water. A virus in a body or a computer system, interacts in such a way as to disrupt the homeostasis and cause the equilibrium to be disrupted, for a computer system this could be failure to boot or exposure to critical information. For a body, this obviously can set off a chain of events that disrupt the internal equilibrium that lead to physical manifestations like a fever, chills, slow or rapid heart beat, vomiting and other symptoms. Both the virus and the sudden storm create violent and/or unusual reactions within those systems, that are contrary with the concept of homeostasis.

At Forres, Macbeth and his wife welcome the thanes of Scotland to the banquet. Immediately prior to the feast, one of the murderers appears at a side door and reveals to Macbeth the truth about the mission: their success in the killing of Banquo and their failure to murder Fleance. Macbeth recomposes himself and returns to the table. As he raises a toast to his absent friend, he imagines he sees the ghost of Banquo. As with the ethereal dagger, the ghost of Banquo appears to come and go, propelling Macbeth into alternating fits of courage and despair. Lady Macbeth invites the thanes to depart and, once alone, tries one last time to soothe her husband. But Macbeth's paranoid mind is already on to the next murder, that of Macduff. To ascertain his future with greater certainty, he makes clear his intention to visit the Weird Sisters once more.
