What does it mean when you dream of a big tunnel?

Answer 1

The train represents your movement forward through time, while the tunnel suggests darkness and inability to see beyond the present moment. Altogether, it illustrates your feeling of being "in the dark" in the sense of not knowing where you are headed.

Answer 2

From a dream dictionary: To dream that you are going through a tunnel, is a bad omen signaling failures in love and in business.

To see a tunnel collapse in your dream, failure and treacherous rivals.

To see a train coming towards you through a tunnel, foretells that you will switch careers.

A different response:

Dream dictionaries assign the same meaning to symbols without consideration of the individual dreamer or the context of the dream. Such interpretations can be quite amusing and fun for parties and conversation. But they are unlikely to have any relevance to the actual meaning of the dream for the individual dreamer.

... From a Freudian perspective, a tunnel would represent the female sex, with the train representing the male. This could be a valid interpretation depending on the gender of the dreamer and other elements in the dream. However, other possibilities are just as likely.

... More broadly, the dream represents the dreamer's emotions at the present time, highlighting the feeling of entering into a dark, depressing or distressing time. The dreamer sees no way of avoiding the dismal situation other than passing through it to the other side.

... Because this dream question was posted at the beginning of the holiday season (Western Culture) it suggests the dreamer's feelings of entering into a series of depressing and distressing dysfunctional family events or dismal holiday activities. Similarly, it could reflect the dreamer's unhappy anticipation of a school term and examinations or the approach of personnel evaluations at work.
