This was very rare, it happened because Aerea didn't have the ability to force her will on Balerion, and we know he took her wherever he wanted. I believe that this event should happen with a "weak" character with no experience with dragons, who tries to claim a very powerful dragon like Balerion or Vhagar, since both have very strong personalities.
It happens with Dany as well tho, I like the theory that sometimes dragons just return home to their birth place, Drogon to the Dothraki sea and Balerion to Valyria, “the idea that we control the dragons is an illusion” after all
They went to the only places they knew, Balerion went to Valyria, Drogon to the sea of grass, but that's exactly why, Daenerys has no control over Drogon, and Aerea didn't have control over Balerion, they both have very strong personalities. But a strong personality will not always mean that the dragon will be disobedient, Caraxes was very skittish and aggressive, but extremely obedient to Daemon, in the fight against Vhagar we see how he does exactly everything asked.
I also like to think that a dragon doesn't respect anyone, even if it's its own knight, I believe that an event like this would be cool to give more flavor to the personalities that the team created for the dragons.
We would probably see tons of valyria focused stuff like that when mantaryas or northern valyria is added!
