On the way to the cedar Forrest to do battle with its terrible guardian, Humbaba, Ekidu interprets a number of ritually induced dreams experienced by Gilgamesh.
Despite the frightening nature of the dreams and symbolism that seems to be deliberately reminiscent of Humbaba, Enkidu assures Gilgamesh that the terrifying images do not represent their opponent and interprets each dream favourably. This behaviour is similar to the way the pair try to bolster each other's courage when they eventually arrive at the cedar Forrest.
As a plot device, the dreams and their innappropriate interpretations serve to build tension as the battle with Humbaba approaches. It may be that the author is deliberately poking fun at or ridiculing official dream interpreters who provide pleasing interpretations or promise victory on the eve of dangerous battles.
Enkidu's dream in the Epic of Gilgamesh foreshadows his own death which ultimately pushes Gilgamesh to seek immortality. Seeing his companion's demise propels Gilgamesh to confront his fear of mortality and drives his quest for eternal life. Enkidu's dream serves as a catalyst for Gilgamesh's motivation to find a way to avoid his own mortality.
In Enkidu's dream in the Epic of Gilgamesh, the underworld is described as a dark and somber place filled with dust, darkness, and silence. It is a realm of the dead where there is no light, joy, or life, reflecting the ancient Mesopotamian belief in a grim and gloomy afterlife.
Gilgamesh is deeply troubled and ponders the nature of dreams and their significance in the context of mortality and death. He begins to fear the inevitability of his own fate and questions his purpose and legacy. This encounter prompts him to reflect on his own mortality and seek a way to overcome death.
Gilgamesh was a King of Ur, he was 1/3 god, 2/3 man. He is devastated by his friend Enkidus death and doesnt want to die also, so he sets out on a journey for immortality. Someone tells him to go find a certain flower that if eaten will give you immortality. HE finds the flower and is going to take it back to his people to share but a serpent takes it on his way back. He goes to the gods to ask for immortality, and a god, tells him that if he can go without sleep for 7 days and 6 nights, then he can become immortal. He fails and falls asleep on the first day, and stays sleeping for all of the 7 days. When he gets home, he is not able to live forever, but he writes down his story, so his story will live forever..
