Act 1 scene four of Hamlet is very short scene in which Hamlet first encounters the ghost. One instance of foreshadowing in the scene is Hamlet's determination to follow the ghost and to do what it tells him. Though the ghost only beckons him and does not tell Hamlet why it wasnts him to follow it, Hamlet does so unquestioning. This foreshadows how Hamlet is going to treat the ghost for the rest of the play. The mood of the scene is tense, one of apprehension. This is clear in the first line that Hamlet speaks, "the air bites shrewdly"
