I dreamed about I ran into an entrance of an ancient South American subterranean tunnel. What does this mean?

Long ago I had dreamed about I got p through a forest to an entrance of an ancient South American subterranean tunnel,then I got into an area which is like alien base.I didn't remember the rest of the dream and been forgot by me,until I saw a book that says about ancient South American underground tunnel recently,and it reminded me about the dream.So,could my dream is being deleted by aliens in order to have me not to tell the public about the mysterious subliminal message hidden in the dream? If so,should I tell the CNN about it?
