Yeah I worked out the "N days without sleep" was mostly rubbish too.

I personally went for 3 days without any sleep in the army as part of a sleep deprivation exercise and it was one of the most brutal things I've ever done, I fell asleep standing up whilst digging a trench, ouch.

So I know when people say "I literally haven't slept in 6 days", they very much don't mean literally, they normally mean they went to bed and had a few hours of sleep per night.
