visual experiments ---- Overlapping fear

I rubbed the text on the paper with the strong smudge effect of toilet paper, because the level of fear in claustrophobic people increases with the length of time they spend in enclosed spaces. The effect of this overprinting can create a persistent sense of fear that a patient has in an enclosed space. Toilet paper has strong permeability, and it also symbolizes that the sense of fear will continue to penetrate into the hearts of patients.
