Although I've never had a brother or sibling die, I can feel the loss of Gilgamesh, like when my she-dog died 2 years ago. That night I was unable to sleep, I just couldn't imagine why they would take her away from me, I had several dreams in which she had come back, dreams so crisp and clear that I thought they were real, making waking up a real pain. I relate this loss to Gilgamesh's. Since he dreams (or more like nightmares) about the eventual loss of Enkidu, his faithful companion and loyal brother. I can feel the isolation he feels, his hatred for whoever controls death and life, his weepings for his brother.
