A Jet being lofty, can indicate being up in your head or too logical with regard to how you go through life or with regard to the subject matter of the dream. Come down out of your head and let your heart have a say in decisions too.
A jet arrival or landing signifies your birth – your arrival onto the planet.
A jet crash signifies a difficult birth – one that was either traumatic emotionally and possibly a life and death situation.
A Jet departure signifies the beginning of a new project or phase of your life. Often these dreams show what is holding you back from the new project. For example, to dream of your partner forgetting your passports for the flight signifies there are problems in your relationship and you are blaming these for not taking the jump.
