Gilgamesh Tablest IV and V

In these tablets we see that the strong bond between Gilgamesh and Enkidu is still going strong, and that they are still together in the long run. Gilgamesh and Enkidu go on a journey of 150 leagues, they get there in 3 days so that means that they walked 50 leagues per day, a feat that would take normal men 3 weeks. This was only achieved because they didn't rest and only stopped to sleep at night and to eat during the day. While they sleep at night Gilgamesh has a lot of dreams and he is scared and thinks he is in danger but Enkidu assures him that everything is fine, I think that th dreams are symbolisms and that they define what is going to happen to them, but Enkidu always makes it look likes its a good thing. They then get to the forest, where they meet the demon Huwawa who starts talking to Gilgamesh, Enkidu quickly interrupts and says that the demon must be killed and that they shall construct a gate with the finest wood in the forest, they slay the monster and suck its insides out and start constructing the gate. In these tablets there are many symbloisms, for example, the gate which means protection, and security. Huwawas head which means that they have slayed them and that they are powerful, among many others. To me these symbols relate to the symbolism seen in the famous book: Lord of the flies. The only doubt I have is: What do Gilgamesh's dreams really mean?
