To dream of lights is a good thing. The opposite of which, is dreaming of darkness, which may be a sign of trespassing of evil forces. Seeing any type of light imagery is good. The light could be from a natural source, like daylight, or artificial source, like lamp light, flash light, smart phone light and etc. A common dream is seeing light at the end of a dark tunnel. This usually denotes that the discovery of a solution to a problem, will come soon. This is good news.
