rainstorms and butcher paper

So I work graveyards, therefore I sleep during the day when I can before I work. Sunday I went to sleep after church because I needed to stay up all night and work. It was raining. In our back yard we have a covered patio. I believe it is aluminum or something similar. When the rain falls it makes a pitter patter noise. Today in my half asleep nonsense I ask O'Ryan, "why are the neighbor's playing with butcher paper?" This makes no sense. I was picturing the neighbors outside with long rolls of butcher paper waving them around making the noises.
