yeah, there are some verses where higher dimensions are just...there, without any transcendence to lower dimensions.
existence of lower dimensions:
It all began with a seed-like black dot. The dot gradually proliferated into lines, criss-crossing each other, eventually into planes. They started building layers and evolved into a completely still sphere.
existence of higher dimensions:
In the center of the universe, Azathoth shut down its physical senses, sinking its consciousness into the depth of the
higher dimension.
Its existence transcended different
dimensions. To be exact, Ithaqua was the
dimensions itself. Ithaqua had access to the past, present and future beyond human recognition.
proof of higher dimensions being superior to lower dimensions:
Mordiggian raised its head to gaze at the great being——Daoloth the creator.
“Ah...how divine it is. I’m just too humble to look directly upon…”
The existence of Daoloth was way beyond its comprehension. Overloaded with messages, Mordiggian’s body, consciousness and even soul were being squeezed.
Eyes, ears, nose started bleeding; skin was decaying; and pain was penetrating through all over its soul. However, Mordiggian’s will was unwavering to maintain direct gaze at Daoloth.
To Mordiggian, the existence of Daoloth remained
incomprehensible.
???: I'm you, and also the origin of all things. You’re lying in my consciousness. This place
transcends space and time dimensions. (Azathoth explaining who he is to Enoch)
Summoner: Huff——Huh? Those were...the memories of the past battles...I’ve been fighting to stop the war on the realm...But where am I now?
This dimension was
boundless and colourless; Infinite star-like speckles were twinkling vaguely, making the black and white space less dull.
Would this suffice for superiority?
