I think you did not understand Lemurian correctly: in a simulator, deliberate use is made of the shortcomings of the vestibular organ in the inner ear.
In order to make the pilot believe he is being accelerated, the simulator cabin is tilted backwards, while the simulator visual could be showing level flight.
In order to make the pilot believe he is being decelerated, the simulator cabin is tilted forwards, while the simulator visual could be showing level flight.
When rolling in, the simulator cabin rolls tilts with the roll, with a rapidity that will be felt by the inner ear. The visual then continues to show proper roll response, while the cabin returns to upright at a rate so low that the inner ear does not detect it, and so on and so forth.
The basic working principle being that the visual channel of man(kind) is so powerfull that it will override sensations from the inner ear. Falling into the trap of the somatogravic illusion is caused by not using the visual channel - not looking at, or not believing, the (artificial) horizon.
Yes, I know how formation flying (as wingman) can topple your "internal" gyro, however, the remedy to that is just a glimpse from the corner of your eye onto your HUD or head down attitude indicator (probably not yet available in old day Tiger Moths).
