You get the membership card in the Canalave City Pokemon market and you go to the house where is locked and it won't open. Then you go to the sailor and you keep talking to him until he say to go to the house that is locked and it will open then the guy with the sun glass will take you to the bed and you well dream a nightmare and you will go to the island where is Darkrai. Then you can catch Darkrai. Please correct me if I am wrong.
