Happens at Night lyrics

I feel something under my bed I hear his sound and feel his breath something moves, creeps beneath me something big, but I cannot see I hear a roar, but nothing shows I'm still tense and my fear grows strange shadows across the light why these things happen at night? I see a shadow running to the wall I begin to scream as he walks he stops, turns and looks at me he goes out, leaving me scared Sleep, my son, was a nightmare Go back to sleep and don't be scared I'll sleep and turn out the light son, these things happen at night
