Was it a dream?

I have had a very unusual dream last night. Or was it real? I am not sure but I thought I over heard my nephew Hamlet talk about his father. Hamlet junior said he meet with his father and he knows about my secret but the whole scence confuses me. How could Hamlet have talked to his father. I mean his father is dead and if Hamlet did not talk to his father then how does he know that I have a secret? I am sure it was a dream that I had of over hearing the conversation between Hamlet and his Friends and night guards. In my dream Hamlet was talking about a meeting that he had with his father and my secret being revielled. But it was only a dream because Hamlet could not have possibly meet with his father. His father; my brother and our late king is dead. There is nothing to worry about. It was just a dream.
