Soliloquy. Because the definition is quite literally <span>an act of speaking one's thoughts aloud when by oneself or regardless of any hearers, especially by a character in a play.</span>
In literature, a soliloquy refers to a speech in which one of the characters reflects about the main conflicts and his/her ideas, thoughts and feelings. Because of this, soliloquies are considered a type of monologue that allows the audience to know the way one character feels and thinks. This type of literary device is the one presented in the passage from Hamlet because in this Hamlet who is the main character reflects about his own life and situation, this can be seen in "To be, or not to be" or in "To die: to sleep; No more; and by a sleep to say we end" that shows the doubts of Hamlet about what he should do and therefore tell the audience about Hamlet's feelings and thoughts.
