The Reverie Dream is the first experience you will encounter upon entering your dreamworld. It acts as a guide to propel you into the world of augmented audio by twisting and mangling sounds from your environment as music from the Inception soundtrack slowly creeps in. Start to perceive the world around you in a completely different way - Our dreams feel real while we're in them. It's only when we wake up that we realise something was actually strange.
Remember in the first few scenes of the film where we find Cobb washed up on the beach. The film focuses on the slow yet relentless sea before Cobb ‘wakes up’. As you begin the Reverie Dream you’ll be showered with the sound of waves that crash around your ears, they are a constant theme that crop up many times. The underlying music of the dream is formed from a previously unreleased string cue playing a melancholic melody while accompanied by disconcerting undertones. It alludes to the feeling that things are not what they first seem. Was that sound you just heard from a passing car or was it just part of the music?
Once induced into the Reverie Dream noises in your environment will be merged into a disturbing soundscape. This is mainly created by a glitcher effect that catches the sounds and randomly pitches and repeats them to make it feel like parts of your surroundings are spinning off into infinity. Because of the randomness in the glitcher any audio processed through it could end up sounding like a drill or some jungle animal for example.
