Floodlights in a dream have a variety of meanings, but generally they signify problems that need your attention. For example, if you are walking in an open field and you see floodlights, it can signal that you are moving in the right direction.
If there are floodlights shining on a house while it is burning down, it means that there is destruction from within.
If you see dark shadowy figures on the other side of a window surrounded by floodlights, then it means that something or someone stole your peace and happiness away from you.
If you dream about getting lost in darkness with just one light to guide the way, then your hope will lead the way out of this difficult situation.
