In Cedar Forest, Gilgamesh has several spiritually significant dreams. Even though they contain frightening events, Enkidu declares that Gilgamesh is safe.
Gilgamesh travels with his friend Enkidu through the Cedar Forest to the mountain. They have been walking a long time.
At twenty leagues they broke for some food, at thirty leagues they stopped for the night, walking Fifty leagues in a whole day, a walk of a month and a half.(Tablet 4)
It is not until the third day that they reach the forest.
In the forest, Gilgamesh has several nightmares. These nightmares are part of a dream ritual with spiritual significance. Enkidu interprets the dreams as good omens, even though they are scary.
My friend, you are so experienced in battle… [you need] not fear death. (Tablet 4)
At that point they continue their journey to the mountain.
