To see beautiful, elegant people dancing to classical music is definitely a positive sign, promising entertainment and lots of joy. If you are attending the ball in a good mood, that indicates that everything is going just the right way. A gloomy mood signifies that you are a bit too strained, so try to relax and forget about your concerns: just enjoy your life the way it is.
If you are attending the meal at the ball, be ready to be invited to a celebration soon. Getting engaged at the ball promises great pleasures to come.
