Woah!!! There's a Ghost in my Bedroom

How would you feel if you saw the ghost of your recently deceased best friend lurching in your room and closet?  I would be freaked out of my mind, I'll tell you that much! Billy although weighing like 23 grams or something, makes quite a ruckus (funny word lol) in Eddie's room and freaks Eddie out so much that he does not talk for weeks, even months.  I wonder how I would have reacted to the same situation...How would you have responded to the situation?
