Absolutely possible. There are threads regarding flight techniques in dreams. A few people have this issue.

Some take a pill, others grow wings, some put on a "jet pack"... it all comes down to confidence. Some people need an "excuse" to believe in this ability to fly. If you believe that the DC has the power to give you this ability, then you will be confident that it will work and expect to fly without a problem.

Whatever works for you. The truth is, you CAN fly in your dream - you don't need anyone's help or approval!
