Wouldn't being on the trees make you dizzy? (no spoilers)

So, please correct me if I missed something, but from what I gather:

- The whole tree spins, except an internal part at the center which is in a vacuum and used to transfer inertia from and to the rest of the tree (making it spin slower or faster).

Wherever you stand it'll be spinning. And unless you're at the center, you'll feel the centrifugal pull.

How can they get anything done without getting dizzy? Just focusing on going in one direction while everything spins...

- People are said to stand on the trees. In what direction? If the tree is horizontal, wouldn't standing vertically be inconvenient because of the spin?

This is a very old question, but they are in a nebula. That nebula isn't like ours, which would simply be vacuum but with a colorful dust to rip out your lungs. Rather, this nebula has enough gravity from its core to allow for oxygen to infiltrate it. But that doesn't mean it's like our Earth or anywhere we can attach to. Rather, gravity is simply SO strong that this seemingly impossible task is possible. Gravity is so strong, humans can feel their own gravity.

Anyway, point is, standing on a tree like this is standing on a gravitational pull like the moon. So when it rotates, it just is stoic for you while the world around you rotates. And so when it changes directions, your stomach may feel that pitch change, but your MIND, your eyes and your ear hairs that cause you to get dizzy, does not feel it. To do so would be to spin with an additional pull of gravity to thus cause the difference of force that you describe. Without that differential, your directional change is nothing, you just are rotating this way and now that way. Your ear hairs, your blood, it still is exactly the same orientation to the tree -- to gravity.

It's very similar to how you wouldn't get dizzy in the spinning ship of 2001, or of Interstellar. Because the spin is causing gravity (not really but just to make the argument concise -- the force exerted upon you we'll call GRAVITY here) which isn't changing your equilibrium but just pulling you in one way relative to your body.

I could be wrong about this mind you, but this is my own supposition from what I've read.
