A tunnel in dreams at times represents the birth canal and, therefore, the process of birth, the transition between the spiritual and physical realms. The image of a tunnel both helps us to escape from the unconscious into the light and also to go down into the depths. A tunnel in a dream usually represents the need to explore our own unconscious and those things we have left untouched. If there is a light at the end of the tunnel in dreams, it indicates we are reaching the final stages of the exploration we have undertaken. If something is blocking the tunnel, some past fear or experience is stopping us from progressing. Finding ourselves in any kind of a tunnel in dreams suggests some kind of constriction in our everyday lives. We may need to focus on an end result to the exclusion of everything else. Going backwards into a tunnel suggest we may have to review the past for answers while working ?blind?. You might also like to consult the entries for Block and Light.
