Questions tagged [illusion]

For questions about illusions, effects or manifestations that deceive the senses or minds of others. They cause people to perceive what is not there, miss what is there, or remember things that never happened. Magical illusions may create phantom images visible to all creatures, but some also plant the image directly in the mind of its target.
