“Mad Girl's Love SongI shut my eyes and all the world drops dead;I lift my lids and all is born again.(I think I made you up inside my head.)The stars go waltzing out in blue and red,And arbitrary blackness gallops in:I shut my eyes and all the world drops dead.I dreamed that you bewitched me into bedAnd sung me moon-struck, kissed me quite insane.(I think I made you up inside my head.)God topples from the sky, hell's fires fade:Exit seraphim and Satan's men:I shut my eyes and all the world drops dead.I fancied you'd return the way you said,But I grow old and I forget your name.(I think I made you up inside my head.)I should have loved a thunderbird instead;At least when spring comes they roar back again.I shut my eyes and all the world drops dead.(I think I made you up inside my head.)”
