The three-dimensional self-boundary visualization (3-DBV) can be a psychotherapeutic tool for exploring inner mental realms by visualizing self-boundaries. The self and its boundaries are represented by symbolic objects which display a simplified image of one’s current emotional and mental circumstances. This three-dimensional setup can then be explored with a self-representing figure from various perspectives. By transferring from horizontal to vertical positions, emotional detachment, and a shift in consciousness to a heightened transcendental state can be witnessed. To evaluate this phenomenon, a study was conducted investigating such changes in perception and comparing horizontal to vertical perspectives. Hereby, 37 individuals were guided through a 60-min, standardized, 3-DBV session via video conference. Self-report questionnaires (CSP and PCI-K-D) and interview transcripts were acquired for a within-subject analysis. The results of which showing that 3-DBV leads to expanded self-perception as displayed in the Changes in Subjective Self-Perception questionnaire (CSP) with an increase of integration in 82%, balance in 65%, and vitality in 73% of participants. The Phenomenology of Consciousness Inventory (PCI-K-D) reveals that the vertical experience induces significantly higher levels of bliss, feelings of expansion, and timelessness than the horizontal. These observations are supported by the qualitative interview data indicating a wider spectrum of emotions, more diverse imagery, and bodily sensations in the vertical plane. Overall, the results demonstrate the suitability of 3-DBV in inciting self-transcending states of consciousness and its potential for future therapeutic use.
