After 3 days without sleeping, the desire to sleep will intensify significantly. Microsleeps may occur more frequently and last longer. Severe sleep deprivation will greatly impair cognitive ability, and hallucinations may become more complex, including: Delusions.

When the experiment ended, Gardner had been awake for 264 hours and 25 minutes. He then had 14 hours of sleep before waking up to use the bathroom.
