Being in jail in a dream can mean several things. On one hand, you may feel unjustly accused of something or limited in some way. The jail can also symbolize your own sense of self condemnation. It can personify a type of guilt that has trapped your free expression. Visiting someone in jail can be a way of exploring what this person represents for you - an old partner can symbolize the power of self-acceptance you have given to them, which is currently restrained. A parent can personify self limiting ideas that you adopted from them. The jail suggests that some aspect of your free and self assured behavior is currently 'locked up.'
