The trick to flying in a lucid dream is developing absolute faith in your ability to fly. Since your mind is projecting the dream, if you have any doubts about flying, you will be unable to fly.
To develop confidence in your ability to fly, there are several methods that can be employed in a lucid dream :
1 • Jump off the top of a high object, then spread your arms like a bird and ‘pull up’
2 • Rocket into the air like Neo or Superman / Superwoman
3 • Extend your arms and spin around like a helicopter – this will propel you way up
4 • ‘Move the dream around you’ with the third eye. This is possible without even moving the dream body. In order to achieve this most exhilarating method, the third eye must be opened and purified through meditation, then it will naturally come.
For best results, meditate at least 20 minutes before sleep, use your favorite dream induction method, choose a flying technique to practice and have fun flying!
