Often we create a ‘prison’ for ourselves through a sense of duty or guilt and this can often be shown in dreams.

The types of locks and bolts we perceive in our prison may show us how we are imprisoning ourselves.

For example, a lock with a key would suggest that we know how to escape, whereas a bolt shows that we have to make a greater effort.

A barred window would suggest that we are being prevented from using that which is external to us.
