Bone #8 (1996)

Phoney Bone's race-fixing scheme continues as he hypes his "Mystery Cow" (who is in fact Smiley Bone in an unconvincing cow costume) to draw bets from the townsfolk. That night, Thorn has a vivid dream in which she sees herself as a young child in a cave and surrounded by dragons. She tells Fone Bone the dream is a recurring one which has only started again since seeing his map. She is certain now that she was the one who drew it, many years earlier, and that her dream is in fact a childhood memory .
