I dreamt repeatedly of spiral staircases last night.
Also, I vividly remember vacuum cleaners as well.
According to this website, my dreams symbolized the following:
To see spiral or winding stairs, signify growth and/or rebirth.
To see a vacuum in your dream, suggests feelings of emptiness. You may be experiencing a void in your life. Alternatively, you may need to clean up your act and your attitude.
Very interesting indeed.
