Do the guards make Hamlet stand with them after seeing ghost?

Yes. In the play "Hamlet" by William Shakespeare, after Hamlet witnesses the ghost of his father, King Hamlet, he is asked to stand with the guards, Marcellus and Bernardo. The guards want Hamlet to confirm the appearance of the ghost and to share in the experience of seeing the apparition. Hamlet agrees, and together they keep watch, discussing the events and seeking to understand the significance of the ghostly presence.
