Sure it can, that's not even fringe science - it's well-established. Don't discount the effect of gravity; it may be weak, but it's strong enough to pull the ocean all out of shape.

Also, the moon is a great big light in the sky. Light affects behavior and sleep - but not through your ears..

You wouldn't need an interstellar object, there are plenty of local objects which can impact Earth too.

Interstellar objects, however, travel faster due to their hyperbolic excess and so would be more difficult to detect.

It would be possible to stop it if it is detected very early and we have a deflector mission ready on the launchpad, the idea behind asteroid deflection is you have a precise orbit for them and impact them early enough such that the small change in trajectory you make is enough to make it miss Earth completely.

In practise, this is probably not feasible.

> Can lunar gravitational forces affect the inner ear?

Technically yes, because gravity reaches infinitely far. Practically no; the moon is 80 times less massive and 60 times farther away than the earth, meaning it affects us 300 000 times less strongly. That's far beyond the sensitivity limit of the human saccule and utricle.

So the meteor known as CNEOS 2014–01–08 is believed to be interstellar. It wasn't detected before entering the atmosphere, but was tracked as it did --
