Highlighter – A highlighter is a dream symbol of drawing attention to certain information. However, you should remember that the area of the brain that processes language is not active during REM sleep, so you are unlikely to read anything in a dream the way you do in waking life – instead, words will change, or speak to you aloud, or appear like a movie, etc. Therefore it is not as significant what you highlight in your dream, since the words will likely have changed the next minute, as the surrounding circumstances. If you are trying to highlight words for the benefit of another person, this indicates that you are trying to communicate something important to them and they are failing to understand it.
