There are two opposite reasons for dreaming about flying.
1 is a dream of feeling good about yourself, being happy and relaxed.
2, eager to escape from reality, away from pressure.
Your dream, I think, represents the second kind.
You say you can fly, but you can't fly high, which is related to your self-ability.
I think I can control my life in reality.
But it is always close to the danger on the ground.
It refers to the insecurity of the environment and the doubt of one's own ability.
