Jail symbolizes your heart and emotions. Specifically it means that you suppress your feelings (keep them captive) and do not share them with others. The logic behind the action is that if people cannot get close they cannot hurt your feelings. Over time you can become so good at suppressing your feelings that you do not even acknowledge them to yourself. For example, a dream where a woman reluctantly releases you from jail means that you are reluctant to open up or share your feelings with others.
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.
