The purpose of this thesis was to gather information on oneironautics as a potential tool for visionary artists. Contemporary visionary art aims to see the unseen and depict it in a visual form that is clear to our ordinary perception. Contemporary visionary artists depict realms that cannot be observed in physical reality. The theoretical part of this study explored the history and importance of visionary art, and the research section suggested practical exercises that can broaden the perception of the mind.

The aim of the case study presented in the theoretical part was to investigate one of the first contemporary visionary artists Ernst Fuchs, contemporary visionary artist Yayoi Kusama, and contemporary artist Dave Green. The key results suggested that oneironautics, a form of lucid dreaming, indeed, can be used as a potential booster for visionary experience and visual enhancements of an artist.

The goal of the practical part was to showcase an installation in the gallery Himmelblau. This installation consisted of four visionary paintings based on the personal experiences of the author, miniature sculptures, and ambient music. The findings based on the research in the theoretical part and on personal art practice indicated that oneironautics is an efficient method of broadening the perception of a visionary artist.
