Noémie suddenly froze, overcome by unbearable dizziness. Her head was spinning, her ears were ringing. The virtual tour of Notre-Dame de Paris had gone well up to that point.

Although she knew she wasn't in any danger, the virtual reality had disrupted her awareness of the real world.
Is it really so easy to alter our perception of reality? Neurologists are now harnessing this malleability of visual consciousness to treat phobias, virtually immersing people in the situations they fear in order to teach them not to be afraid of them anymore. Hypnotic suggestion can also plunge us into a state different from ordinary wakefulness.
