Dreaming of vouchers suggests that consistency and honest effort will outlast any attempts by rivals to undermine you or redirect your path. Stay the course, and the schemes of others will lose their grip.
If you're signing a voucher in the dream, it reflects the trust people around you have placed in you — even when others are working against your interests, your support system remains solid.
Losing a voucher points to a coming dispute, likely with family, over what you're owed or what's rightfully yours. Expect to have to advocate clearly for yourself.
