Flying is symbolic of projecting your mind and this means three abilities are part of your nature. The first is absent healing – which is healing from afar. This is what Jesus performs on the centurion’s servant in the bible.
The second is that you have the ability to project your mind onto others. You can use this to good and bad effect. It is very useful in marketing, sales and teaching. Be careful not to think badly of others, as your negative thoughts can have a negative effect on them. Whether you believe in karma or not you will bring it on yourself for doing this.
The third is the ability to hypnotize others. Hypnosis is achieved by the practitioner projecting their mind onto their subject. This is regardless of other tools the hypnotist may use or believe is doing the hypnosis for them. It is their mental projection onto the mind of the subject that makes it work.
Flying with a guide in a dream indicates you are a channel. You can travel to the spirit world to communicate with spirits and bring back the messages you receive. A guide is anyone with a title, anyone who speaks with authority or anyone who offers you a gift in a dream.
