When you reach the part of sleep deprivation where you start to feel tipsy or even outright inebriated. Regardless of sleep deprivation's severity, you can feel either slightly tipsy or absolutely smashed, or ANYWHERE in between; however, it's generally more severe the further you slip into sleep deprivation. Sleep inebriation is usually in the form of scenes separated by unreasonable emotions such as apathy or sorrow, but can be a constant intoxicating feeling.
