Flying, being chased, and appearing naked in public are all common symbols that appear in dreams. Other common dream symbols include falling, death and being trapped.
Many people have experienced a dream in which they appear naked at school or work, and researchers say this type of symbolism is related to feelings of vulnerability and nervousness. Death is also prevalent in many dreams and is thought to symbolize the desire to end a particular thing in the dreamer's life. Similarly, killing in dreams can signal the dreamer's desire to change a certain aspect about himself. Sex, teeth and authority figures are also common dream symbols.
