To see a tunnel in your dream represents the vagina, womb, and birth. Thus it may refer to a need for security and nurturance.
To dream that you are going through a tunnel suggests that you are exploring aspects of your subconscious. You are opening yourself to a brand new awareness. Alternatively, it indicates your limited perspective as in the phrase “tunnel vision”. Are you being close minded or narrow minded in some issue?
To see the light at the end of a tunnel symbolises hope. You will navigate through life and all its difficulties with great success. Alternatively, it also indicates the end of your journey and the realization of your goals.
