Number Twelve

You begin to ride your bikes home when suddenly, a bus comes out of the middle of nowhere.  It strikes you and your friend, killing you instantly.  When you come to your senses, you realize that your a little transparent and attending your own funeral.  Considering yourself a freak, you return to the haunted house, bent on haunting your dying place and scaring away all those that dared enter the house before it was too late.

For reasons you don't understand, your friend somehow managed to pass on to the afterlife, you suppose it has something to do with the strange air you breathed while inside the house when you were alive.
