This paper examines the experience of lucid dreaming both from my own perspective and that of others, as well as the theoretical, psychological and artistic aspects of this phenomenon. I discuss destabilizing factors in lucid dreaming: a term used to describe things that normally do not happen or exist in reality as well as the feeling and perception in lucid dreams that persist in the waking state. I examine the research question: how might light be used to evoke a destabilizing feeling and perception inspired by lucid dreams in an art installation? I describe three installation projects that address this question.
