Gollum's Dissociative Identity Disorder In The Hobbit

Personally, I believe Gollum has dissociative identity disorder. Though he appears to be talking to himself saying things such as, “What shall we do?” (Tolkien 86) or “Curse us and crush us, my precious is lost!” (Tolkien 82), it seems to me that Gollum speaks as if he is talking to another person. After consulting Alvien about my theories, he reveals to me that Gollum was previously a hobbit named Smeagol like Bilbo and that Gollum appeared only after he got the ring. Although the name “Smeagol” was never mentioned in The Hobbit, during the riddle battle, Gollum recalls memories of a past suggesting him being a hobbit. This further supports my idea of dissociative identity disorder because we can clearly see two distinct personalities: Smeagol and Gollum. Now Gollum remains stuck where he is obsessing over his “birthday present” or the ring.

The rest of the group is thrown into the Elvenking dungeon except Bilbo, who manages to escape with the ring’s power. Bilbo follows and plans for escape. He rescues them all by placing them in barrels and barrel-rolling to safety.
Reunited, they continue on their journey. They are now nearing their final boss, Smaug the dragon, in Lonely Mountain. At first, they are confused as to what they should do, but soon they figure out that they must use the runes previously translated by Elrond.
Inside they find Smaug sorting I the treasure as if he were the crab, Tamatoa, from Moana. Despite this being the first time I mention it, The Hobbit includes so much singing it's basically a musical. In this post I thought about Smaug singing the shiny
