Dreamscape (NIF)

In Niflheim's World, the Dreamscape is the plane of existence where the consciousnesses of all living beings reside.

Description
The Dreamscape is a dimension connected to Niflheim's World that houses all the living consciousnesses that reside within that universe, regardless of whether its inhabitants are aware of its existence or not. The Dreamscape is impossible to describe in its default state because it contains nothing but thought; but telepaths who are skilled enough to consciously visit the Dreamscape through the creation of a mental avatar can see the thoughts of others and themselves visualized as words travelling across the blankness of the dimension. Especially powerful telepaths who visit the Dreamscape can also alter how the dimension appears to themselves and others by creating telepathic constructs, and can remotely manipulate the minds of lesser beings by locating their consciousnesses within the Dreamscape and manually editing their thoughts.

In the third dimension (otherwise known as 'normal space') of Niflheim's World, powerful espers can draw upon Dreamscape-specific energy named 'Kø' to manifest superhero-like abilities in the real world.

History
Niflheim had spent some time in the Dreamscape of Niflheim's World and had learned how to navigate it.

In 150,084 CMT, Niflheim was fighting a battle in the Hell of Niflheim's World when he was suddenly 'knocked out of' reality and transported to an entirely different Hell altogether: the Hell of the Original Universe. When Nif did not return from his mission to Hell, his close friend Mina Bjork tried to establish communication with his consciousness in the Dreamscape so that she could learn his location, but discovered that his consciousness had disappeared from the Dreamscape altogether. Mina refused to consider the likelihood that Nif's consciousness was not present in the Dreamscape because he had died, instead choosing to use her time-travel abilities to send her consciousness through the Dreamscape and into alternate timelines in case he had been transported forwards or backwards in time. To prevent the journey from tearing her psyche apart, Mina had to keep herself focused on a 'constant', a concept that was present in each alternate timeline she chose to visit. Mina's constant was her friendship with Nif, which existed both in Niflheim's World and would soon exist in the future of the Original Universe.

Mina's search eventually brought her consciousness to the Dreamscape of the Original Universe, where she established contact with Nif's consciousness while he was asleep on Day 76 of The Mazkertis Paradox arc. Mina briefed Nif on how she had managed to find him and shared her theory as to how Nif had ended up in the Original Universe in the first place: that a catastrophic temporal event had caused Niflheim's World to diverge from its natural timeline and develop into another universe altogether (which may or may not be the Original Universe). Mina explained that because Nif had been in Hell, a dimension that exists outside of time, when the theorized change occurred, he had been transported to the same place in Hell in a different timeline altogether instead of normal space in Niflheim's World when he had been 'knocked out of' Hell. While Nif processed this new information, Mina clarified that, in order for Nif to return home, he needed to focus on a 'constant' like she had in order to prevent the cross-timeline travel from tearing his psyche apart. Mina explained that Nif's constant should be his friendship with her, Drepp, EEEEEE, and other close friends of his that existed in both universes. Nif protested that he had not yet befriended the Original Universe's versions of the friends he had in Niflheim's World, but Mina replied that he would and that it was the only way he could return home.
