What is the theme in The Book of Disquiet by Fernando Pessoa?

Dreaming is one of Soares' favorite activities. Therefore, he writes about the activity frequently. It is through dreaming that Soares is able to escape from the reality of life that he finds both depressing and distressing. In Section 92 Soares writes that it is the act of dreaming that has given meaning to his life. It is through dreams that Soares escapes from the sorrows of life. In Section 163, Soares writes that through his dream life, he can have the same experiences as someone who actually performs the activities. Soares condemns people who participate actively in direct experiences as lacking any imagination. In Section 173, Soares refers to dreaming as a natural drug. He writes that once one has taken this drug, they are unable to get it out of their system.
