Most of the dreams we have are due to anxiety,” said Adele Nozedar, author of the book “Freaky Dreams: An A-Z of the Weirdest and Wackiest Dreams and What They Really Mean” (HarperCollins). “The highest proportion of dreams that we have is about things we are worried about.” Nozedar, who studied psychology in the U.K. and wrote two books about the meaning behind signs and signals, analyzed over 150 dreams for her book. They ranged from the bizarre — “I was throwing Phil Collins’ chicken off a cliff”— to funny— “I dreamed of a children’s story that features an amazing creature that’s half butterfly and half mermaid. She’s called ‘Buttmaid.’ ” There were also the recurring themes such as losing your teeth, not wearing any clothes in public, being chased, falling, flying, and not being prepared for a test. “All of the most popular recurring dreams have to do with some sort of anxiety — such as fear of exposure, loss of control, and not being prepared,” she said. “The only one that doesn’t is the flying dreams. If you’re soaring above rooftops this is great. It implies confidence in yourself and satisfaction with your life.
