Dream of grandpa, person

I was having a friend stay over and i decided for fun to show my friend how i can talk to my dead grandpa threw my magic book. it was a book that for some strange reason has water in it and when i looked into the water i could ask for a person that had passed away and they will come to the book to talk to me. So i asked for my grandpa who had passed away two years ago for some reason they could not find him they said he had been taken to the south end of heaven which was where bad people go but i didn't understand because my grandpa was a good guy. But when i finally got to talk to him it didn't really look like him it said it was him but it kinda look like a celebrity i was seen on tv when i was a little girl and the celebrity who is also dead too. Does this dream mean i was visited by my grandpa in my dream
