Any dream that you have that features boys in any activity is a good omen and bodes well for the dreamer in whatever he/she is undertaking at the present time. Of course, if the boys are injured, or otherwise beset, then you must take the dream to mean an ill omen.
Brakes: Brakes are a warning dream, and more so if you dream that you braked a vehicle and the brakes failed.
Failing brakes are a warning not to accept a new offer that you have just been presented with, as there are well hidden snags that can harm more that help.
The action of braking itself is an idiom telling you to ‘put the brakes on’, whether it is business or love, or even some impetuous act that could cause you legal trouble. You should also check your brakes on your personal vehicle.
