Vision, Perception, and Belief in Act I, scenes i and ii of Hamlet

After reading Act I Scene i and ii, the ghost seemed to be a big part of then play and seemed to bring everything together. At first, the fact that he did not speak to Horatio, Bernardo, and Marcellus seems to make his appearance even more mysterious and makes the readers suspicious. The idea of the ghost being used in Shakespeare's play raises new ideas of how he wants his writing to affect people and what he wants people to believe when they read his writing. Our own beliefs affect what we believe and how we read this play. Different perceptions give different ideas on how all these things used in the play come together and play an important role in the play.
The ghost continues to play an important role in the play as Claudius reminds Hamlet at the announcement of his recent marriage to Gertrude, that he should think of his father and remember his mistakes and well-doings to learn to be future heir of the throne. This shows that what we believe in and our perception of a ghost, something that appears and disappears is what shapes the way we read this play and the importance of every detail. Someone may see the ghost as a small part of the play and others may see as very important.
I don't believe in ghosts but I do believe that sometimes theres a spirit of someone really close to you that has either unfinished business with you or loves you can stay with you even after their death. Sometimes this may just be a sign of how the person cannot let go of their loved one but sometimes it may even be real. The fact that other people are made out to see the ghost as well in Hamlet shows that it is not just in Hamlet head and this thing might actually be real.
