The first picture, 'Derealisation', describes the relationship between different versions of reality. The desaturated rectangle signifies the reality perceived by a person experiencing derealisation, a dissociative symptom in which the world seems unreal.
The second picture, 'Depersonalisation', describes a feeling of being detached from one's sense of self. The circle represents a mirror, and the ides of viewing an "unreal" image of oneself through the mirror, while the true self exists somewhere beyond perceived reality.
