Reverse gravity in some areas in the nether

As the nether is a disorienting dimension where the compass doesn't work and where there is a strange roof with no explanation of the stability of this dimension.

It would nice to have a reverse direction of the gravity in some areas.

The items, the lava and player falling in the other direction than the classic 'up to bottom'.

Maybe some area where the gravity is nullified in order to make the transition between the areas.

Even the generated structures in these areas could be generated backward.

This would be more fun to explore the nether. :)

Building a base on those anomalies or between them can be very interesting and challenging.
