Storytelling entertains, educates, and inspires people of all ages and a compelling story has the power to motivate, elicit emotions, behavioural change, and inspire self-reflection. Interactive Digital Narratives (IDN) offer, arguably, a greater potential for impact on their audience due to the participative nature of interaction whilst storytelling in Virtual Reality (VR), benefits from high levels of immersion. This work focuses on the design and development of compelling narrative elements towards a non-narrated and unguided VR experience aimed at portraying and evoking emotions, moods, and self-reflection. We explore how the combined elements of light, colour, shape and music can play a role in creating compelling stories and influence users within an immersive VR experience. Finally, this article presents an extensive study of relevant literature, the design of an impactful immersive VR narrative experience and an exploratory practice-based study.
