Answer:
I do not see choices, but I hope that this helps.
I do not believe that Hamlet was crazy and saw hallucinations of a ghost. He had some problems, but other people saw this ghost before he did. Other people have discussed what they saw and this is not in Hamlet's imagination. He could be really sad that his Father has died, but did he really lose his mind? Probably not.
Step-by-step explanation:
Since others saw this same ghost, it is not in his head. The ghost is realllllll.
