There are those who sleep. There are those who don't. Tormented by insomnia, lack of air, incontinence, intestinal gases, rheumatic pains, nocturnal coughing fits, bronchitis, remorse, fright. Sleepless nights, easy victims for backyard demons, invisible from the street. Nobody sees it, but the backyard ghost is there, attentive. Nobody can free themselves of evil!
