A dream dictionary can be handy, but typical definitions only apply about 50% of the time. There is a definite "gift of interpretation" the Holy Spirit gives some people. The Holy Spirit will provide the meaning for the other half of the dream symbols. Also, our Guide may develop a "dream language" with us where the same items will often have the same meaning. Another factor is the country where you live. A green light may mean "go" in America, but it may mean "caution" elsewhere.
You can post your dreams here on my dream forum and I will interpret them as the Holy Spirit reveals them to me.
