What does it mean?

I have many different dreams in which this happens and it's always different but the same. There are fish swimming in a tank or glass bowl. all the sudden they are swimming out of the tank into the air, but it's as if the air was water, they swim on like there is no difference. I almost always try to put them back in the tank, afraid that they'll die from being out of water. Sometimes they start of as goldfish and become exotic fish. The dream is never frantic or peaceful, it's a weird lucid feeling when the fish start floating. I've tried to find a meaning to flying, or floating fish, but have found nothing. Is there anyone who can tell me why this keeps happening in my dreams? Tweet
