Svp si vous connaissez la legende irlandaise "the dullahans" aidez moi juste pour corriger mon résumé

a long time ago it was a headless horseman. he is named dullahan. he had a black horse and he carried his head sometimes in his hand or in the saddle of his horse. the head was shiny . everywhere the dullahan stooped a mortel died ! but there was just one way to stay alive : showing him gold.
bien sur si vous avez des ameliorations ou vous proposez d'autres chauses ecrvez la en anglais. et surtout n'oubliez pas de me corriger mes fautes. et merciiii
