I have a strange fascination with the psychology of sleep. Yesterday, (call me a dork if you must) I found myself leafing through my sister's AP Psychology textbook in a chapter about sleep. There's something about it that's a mystery, one of the only parts of our psyche that has questions unanswered and ideas un-explored. So, I've decided to assemble a random assortment of interesting facts about sleep (yes, I'm one of those people that can spend hours just reading random facts).
1. The record for longest time without sleep is 18 days, 21 hours and 40 minutes. Sleeper reported hallucinations, slurred speech and paranoia.
2. Humans sleep, on average, three hours less than most other primates.
3. 12% of people dream in black and white.
4. Giraffes sleep for only 1.9 hours a day.
5. Within 5 minutes of being awake, half of your last dream is forgotten.
6. We can only dream of faces we've already seen.
7. 1 out of 50 teenagers still wet their bed.
8. People who don't dream generally have personality disorders.
9. 1 in 4 married couples sleep in separate beds.
10. Koala bears sleep for 22 hours a day.
Well, I found it interesting.
