Dreamweaver's Conclave

You weave a spell that binds the dreams of up to six creatures known to the caster within a 5 mile radius, including yourself, into a shared lucid dream. This spell must be cast immediately before taking a long rest and all who are targeted by the spell are invited into the shared dream when they fall asleep during the duration of the spell. The invitation of which appearing in a manner the caster chooses, such as an opened door, a figure, a portal, etc. If accepted, the participants' consciousnesses are transported into a shared dream world while their bodies remain in a restful slumber in the physical world. Creatures that don't sleep, such as elves, can't be contacted by this spell.

The caster has the ability to shape the environment and entities within the dream, creating landscapes, objects, and other images. The caster may also choose to eject a participant from the dream as a free action. In the dream world, participants can interact as if they were awake, able to converse and strategize, use items they had on their person at the time of casting, and even practice skills. Items brought within the dream can be interacted with as if in the waking world. So much so that an item crafted within the dream will persist into the waking world. But any crafts must use real tools and materials that are already within the creatures possession upon entering the dream. Dream entities cannot shape or affect real objects, neither can entities made purely within the dream be taken out of it.

Items can be traded between participants within the dream and those items will be in their possession in the waking world. Items cannot be stolen from another participant and must be a mutually agreed trade. While consumables in the dream can be made such as Food and Drink for enjoyment, only real consumables brought within the dream have tangible effects outside of it. Participants cannot be damaged or harmed within the dream.

While in the dream, participants are dimly aware of their surroundings in the physical world and may exit the shared dream at any time. They may gain the benefits of a Long Rest as normal. Additionally, for 1 hour after waking, participants gain a +1 bonus to all ability checks and saving throws, reflecting the mental clarity gained from the shared dream experience. 

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 4th. At 6th level, the spells range increases to any creature on the same plane so long as the caster is familiar with the target.
