The Big Dictionary of Dreams

by Martha Clarke
In dreams, cameras usually represent yourself. The vision obtained through the lens is probably more impartial than the vision obtained through the eye. So dreaming that you photograph something or someone probably indicates a desire to see that thing or person in a more objective and less emotional way than you would in real life. It represents your desire to better focus on a particular person or situation.

If the camera does not work well or when developing the picture the image is not clear maybe you are avoiding an issue in real life. It can also refer to your desire to revive the past and keep it forever.

A camera allows you to record and document the important moments of your life. In this way, it is a symbol that relates to an extension of your memory. This is becoming more ubiquitous in modern culture with the advent of digital media, and the camera’s reach is more and more about a constant collection of data and self-expression.

A camera in your dream may relate to a desire to be public about your experience and to continually reflect about where you have been in your journey.
