Gawain wandered in this lucid dream realm.
He didn't know the theory behind such a change, but he guessed that the reason for this change most likely had to do with that heretic of the Eternal Sleepers —— in the process of engulfing those remaining shards of consciousness, he came into contact with the gleanings of Eternal Sleepers. Those gleanings weren't as simple as mere memories. As 'knowledge' of the Beyonder realm, it itself was a form of power.
They brought Gawain the ability to be active in such a lucid dream realm.
Gawain walked while molding some items in his hands according to what he had in mind from time to time and discovered the limitations of such molding in this process. Probably because he had not acquired the true power of the Eternal Sleepers, the items that he molded in the dream realm were still 'imaginative' in every sense. They merely had appearances that could be passed off as real ones but had no true function.
