The general rule is- you can't sense velocities without a reference frame, but you can sense accelerations. So, you're in the back of a semi truck, no windows, moving down a smooth road. You can't tell if you are driving at 100 km/h or sitting still, nothing is different. But you can tell if the truck is traveling at a constant speed (or even no speed), or accelerating. When the truck accelerates, you will feel like you're getting pushed towards the back of the truck. Or even if the truck maintains a constant speed, but goes around a corner (this is like your spinning example) you will feel like you're being pushed to the side of the truck.
Velocities are all relative, cannot be sensed. Accelerations are caused by forces, can be sensed.

while searching for a better description to describe my struggle, i found some hints i will try to follow:
- Mach's principle vs Newtons Rotating Bucket...
- General Relativity: Lense-Thirring-Effect and Brans-Dicke-Theory
might be that a universe consisting of single rotating object would drag space with it ?? Thank you anyways !!
