Trait: Confinement in a Simulated Reality
This character is confined in a simulated reality, involuntarily or voluntarily.
While this trait applies to anybody confined in any kind of simulated reality, the "Lotus-Eater Machine" scenario refers to a specific variety of confinement in a simulated reality. In this, a character, usually the protagonist, is knocked out or goes to sleep and wakes up in their own personal paradise. In reality, they're being held prisoner by another character who, using technology, magic or other methods, induces very intense and very realistic hallucinations. Sometimes the lotus-eater doesn't know it's all fake. Sometimes they do know but don't care. [Edited from TV Tropes]
