It is a bad omen, you have to be very careful on financial matters, so as not to incur losses. Someone will not keep the promise.
see or receive: you must wait until someone will be able to fulfill the promise given to you, because he/she will keep it for sure
a check without a signature: important discussions
a check without the defined sum: illusory payment
carry out a check: the success of interests
false check: carefully think through your decisions
issue: do not promise anything, you will not be able to realize
lost checkbook: the loss of your own authority, influence, prestige and opportunities to impress others
find a strange checkbook: you will inherit from someone an important function, or you will replace someone on a high position.
