A prison represents the limits you feel imposed on your freedom, whether from external circumstance or your own beliefs. Being imprisoned in a dream often points to a situation, a habit or a fear that holds you in place. A prison you can see out of, or a door left open, suggests escape is closer than you believe. This dream asks you to name exactly what is confining you, and to separate the real constraints you cannot change from the self-imposed bars you have the power to unlock.
