If you committed a crime, it is not necessary to factor that in for the dream interpretation of being arrested. The idea of being arrested in a dream has issues that have to do with control This may be self control in one way or another, but it usually relates to control issues from other entities, or from yourself depending on perspective. With that in mind, continue reading.
When you have a dream where you are the one that is being arrested, this usually means that you are feeling a bit boxed in. Not only is no one listening to you or accepting your validity as a human being, but you also feel that your protests are having absolutely no effect on your peers. This is usually the kind of interpretation that might work for you if you are working on a group project and nobody is taking your suggestions seriously. It might be high time for you to take a little more leadership on. Force people to listen to you and they will respect you if your ideas are good.
Another reason you could be having this dream is if you are being pushed around by an annoying boss or employer and you feel that you are being forced into a submissive role that does not fit your personality. Of course in a case like this you cannot really fight back unless you are okay with losing your job. It might be helpful to come to terms with your boss though. Try seeking to have conversations with them outside of the context of work, such as on a mandated lunch break, or even ask them to go out for drinks with you. You can learn a lot about someone through these methods, and you can find some common ground to relate to that will make both of you happy with the other one.
Of course you will not be able to be so friendly so easily on just the first outing or conversation, but over time you can grow to reach an understanding with one another that will make the work place more bearable and you will not have to worry so much about being forced into a role that you do not like to be in.
If you are dreaming that you are the one that is arresting someone else, then conversely this usually means that you are degrading the importance of someone else. You are making them feel low or useless and forcing them to do things for you. You are too controlling of them. While this relationship may be productive for a while, the employee morale will slowly decrease until you are left with nothing but sorely angry employees (or even friends if you are not a business manager) that will not respect you anymore. What is more important to you, business, or interpersonal relationships? Ask yourself this when you start having dreams where you are arresting others.
