Artifact: Gate of Lost Dreams

Level: 1d6+4
Form: A hoop of thin metallic wire, easily twisted and curled into a small bundle that can be carried in a pocket; when active, the loop stiffens and becomes immobile, with a swirling prismatic mist filling it.
Effect: This numenera artifact gives access to a pocket universe built from the merged subconscious dream-state of everyone within a short range at the moment of activation. Passing through the portal provides physical access to this realm, where the rules of physics often take their leave completely, in ways that not even the strangest ruins of the past worlds permit.
The world has both risks and rewards - all the fear, worry, and hatred of a person who gave shape to the world is manifest here, in some form; fighting and defeating these things will cause a corresponding change in the mental state of that person for the next week; repeated destruction of these negative aspects can, over time, create a permanent change. Given their nature, however, none of them are easy to defeat - the level of the artifact determines the level of the creatures found in the pocket dimension.
Items found in this space can be taken back out through the portal, functioning as numenera devices in their own right; when used, they discorporate into thin slime, their essence returning to the awareness of the person from whom they were harvested.
One final risk/reward of this altered realm is the ability to relive memories and even transform them - a powerful tool for therapy, as events that cause grief can be mitigated in memory while positive memories can be reinforced. It serves as an equally powerful tool for those seeking hidden information, however, as the ability to step bodily into a memory and search it for secrets is not to be underestimated.
No one knows what happens if the Gate of Lost Dreams is deactivated while someone lingers in the dreamworld on the other side; none lost in such a way have ever been seen again.
