Dream sharing is the practice of creating a dream and bringing one or more people into that new dream world. While dream sharing, the dreamer creates and controls the world, while the subject populates it with both people and information.
To initiate dream sharing, special medication is needed and is facilitated by the PASIV device. Somnacin is one of the drugs used for this purpose.[1] When dreaming on level 1, a timer mechanism on the PASIV device can be used to wake up dreamers. Multiple dream levels require a method known as a kick to awaken from a dream on a deeper level.
Time within a shared dream moves differently than in the waking world. The medication required for the experience and the mind both creating and perceiving its own reality causes the perception of time to elapse far slower within a dream. This Time dilation causes dreamers to experience hours, days, months and even years within a dream space while far less time has passed in the waking world.
Dream sharing was first utilized by the military to provide a realistic training method for soldiers, in Project Somnacin.[2] Underground circles have also utilized dream share for entertainment purposes, such as "dreamcades" for challenging others and creating dreams for leisure.[3] In Inception, dream share is used to commit extractions by stealing information and inception by planting information in the form of an idea into the mind of the subject and making the subject think that the idea is their own. Miles brought Dominick Cobb and the others into dream sharing to prove to them that their creativity was limitless.
Overexposure to dream sharing can cause an individual to be unable to dream naturally. Many people who can no longer dream must use a PASIV device if they wish to dream while they sleep.[4]
