The rooster crows.
Not real ghosts, presumably, but stage ghosts. Ghosts appear in the following Shakespearean plays: Hamlet, Julius Caesar, and Richard III. In Hamlet, the stage directions say only "Enter Ghost", which could mean that he entered through the same doors of all the other actors. Indeed in Act 1 Scene 5 he must enter through the same door as Hamlet as Hamlet is following him. The same can be said for Caesar's Ghost and the Ghosts in Richard III. They could also appear on the balcony. Using the trapdoor would have been awkward and ineffective.
Yeah, cause Hamlet's a dork
All the world is a stage and men and women are merely the players (Hamlet)
Metafiction
Very few, since the leads are more often than not male roles. Not that this has stopped some actresses. Sarah Bernhart's Hamlet was much remarked on. So was Charlotte Cushman's Romeo (she preferred the male roles anyway). Diane Venora has not only played Ophelia (to Kevin Kline's Hamlet) and Gertrude (to Ethan Hawke's Hamlet) but has also played Hamlet, although on stage, not on film. The roles of Cleopatra and Rosalind (in As You Like It) are the closest Shakespeare comes to true female leads, and every Shakespearean actress worth her salt has had a whack at them.
The ghost, in Act 1 Scene 5.

On the stage, usually. Sometimes under the stage, like the Ghost in Hamlet, or over it, like Jupiter in Cymbeline, or on the balcony behind it like Juliet in Romeo and Juliet or the Mayor of Harfleur in Henry V, but generally on the stage.
King hamlet, hamlets real father is already dead, poisened by claudious before the play begins, he is the ghost. then hamlet accidentally kills polonious.
A number of things, obviously. The Ghost is still bellowing "Swear!" from under the stage. And we can assume that Claudius is still partying as he was earlier in the previous scene. What else is happening, we don't know.
At his time, there were no props, no backstage, every character entered the stage on his feet and exitted the same way, except when it was dead. In this case the authors had to write lines such as "Carry this ugly/sad corpse away, soldiers!" and out he went!
The ghost of king hamlet tells hamlet that Claudius killed him, then hamlet puts on a play in front of the king and everyone else about how a man kills a king then earns the love of the queen. Claudius jumps up and runs out, therefore the ghost spoke the truth and the murder had been confirmed
This is from Hamlet. What it means is that Hamlet suspected his father was murdered. Which he was, but at that stage he didnt know this.
Well, a lot of people: Hamlet, Claudius, Gertrude, and Laertes.
Unless you think a ghost is a "legendary creature", there are no legendary creatures which are in the cast list or appear on stage in the play. Legendary creatures are referred to from time to time in the text, as "as was to this Hyperion to a satyr".
