The forces that usually plague a person after he or she acquires a considerable sleep debt by sleeping very little (or not at all) for extended periods of time.

Sleep debt loan sharks may use schemes such as spontaneous microsleep, low cognitive capabilities, and (if the sleep debt is extraordinarily high) auditory and visual hallucinations, in order to make a person pay off his or her sleep debt.

As with regular loan sharks, sleep debt loan sharks can be staved off temporarily. In this case, it is through the use of psychostimulants, such as caffeine, amphetamines, ecstasy, cocaine, etc.
