Why did Ariel make everyone fall asleep in the tempest?

In William Shakespeare's play "The Tempest," Ariel puts everyone to sleep as part of his service to Prospero, who seeks to orchestrate a series of events to achieve justice and reconciliation. By putting the shipwrecked characters into a deep slumber, Ariel allows Prospero to manipulate the situation without interference and create opportunities for confrontation and resolution. This act serves to highlight themes of control, power, and the interplay between magic and reality within the narrative.
