Everyone has to sleep at some point or run the risk of sleep-deprived illnesses.
Not to mention the immediate drowsiness and general irritable feelings in the morning from the lack of sleep.
However, when we sleep, our brain is still active, and this helps us to dream.
Alternatively, it gives us nightmares, depending on the situation.
If you don't plan on having sweet dreams tonight, have a look through the gallery, and stay awake till morning.
