Scales in a dream suggest the necessity for balance and self-control. Without that balance we cannot make a sensible decision as to potential courses of action. We must ‘weigh up’ all the possibilities.
Scales will also suggest standards – for instance, standards of behaviour – to which we are expected to adhere. We may be weighed and found wanting.
If the scales are unbalanced in a dream we need to search our conscience and discover where we are not functioning properly in our lives.
