You CANNOT die from a lack of sleep.
Unless you get in a car, fall asleep, and crash, but just from not sleeping, you won't die.
Some people get really weird after 1 day with no sleep. Others are fine, like me. I have sleep problems, I'll go days without sleep.
The longest I've gone was 4 days, and I was fatigued, my muscles hurt, I couldn't focus or concentrate, got irritated easily. I didn't hallucinate, but within a few days I would have.
So, you're just gonna get more tired, irritated and cranky, and maybe hallucinate.
