I understand.
But the feats and statements I just post is not piece together and said dimension is not universe, it is directly stated to be dimensions, the universe is universe is seperate.
"A really powerful vortex that drags into itself anything that comes into its trajectory. A vortex made up of an infinite number of well, levels for want of a better description. And if they seem to diminish as they get towards the bottom of the vortex, rest assured, it's an illusion. For this vortex has no bottom. It is, being constructed of chronon energy, and thus temporal in nature, endless. Eternal. Bottomless, topless, middleless."
The statement was referred to the Spiral, which formed the axis of Time Vortex.
"Monica looked up to the ceiling. 'I'm coming for you, Doctor!' And in a flash of light she resumed her Lamprey form and vanished straight into the heart of the Spiral that formed the axis of the space-time vortex."
The levels is confirmed to be dimensions many times, like:
"'How! How can you touch me! I'm intangible. I am across all time and space. I am everywhere at once.'
'No,' the Doctor said, pained, exhausted and just a littleangrily.
'You are trapped here. By me. One solitary individual against your omnipotence. And I will beat you.'
'How?'
'Because I am... the... Doctor!' And he threw himself into the spiralled crucible, dropping downwards into the dimensionally transcendental abyss, accompanied by the screeching Monica/Lamprey, sending shards of blue light around them as they fell."
And
"the energy from the assembled Doctors battering the two figures, distorting them along every dimensional plane"
And
"For millennia, scholars have tried to fathom the true nature of what they have come to refer to as 'The Spiral'. They have failed because, of course, they cannot tell whether each time they examine the Spiral they are seeing it exponentially or randomly.
It is theorised that creatures live within the confines of the Spiral, creatures that have access to multiple dimensions"
And
"Rummas had crossed the room to join her. 'It's a sacrifice, across time and space. Across universes and multiverses. Across dimensions and ―' " (This one directly seperated the universes, multiverses, and dimensions)
