Solipsism syndrome is a state of mind in which a person begins to feel that everything is a dream and is not real.
Solipsism is a
philosophical theory that everything is in the
imagination, and there is no
reality outside one's own mind. As a philosophical theory it is interesting because it is internally consistent and, therefore, cannot be disproved. But as a
psychological state, it is highly uncomfortable. The whole of life becomes a long dream from which an individual can never wake up. Even friends are not real, they are a part of the dream. A person may feel very lonely and detached, and eventually becomes
apathetic and indifferent.
Some environments are conducive to producing solipsism syndrome. This state of mind can be easily produced in an environment where everything is artificial, where everything is like a
theater stage, where every wish can be fulfilled by a push-button, and where there is nothing beyond the theater stage and beyond an individual's control.
Several strategies to alleviate the tendency toward the solipsism syndrome in artificial environments (such as man-made habitats in outer space or under water) are discussed in
