We spend about one-third of our life sleeping. Although from the outside it seems like nothing but a routine, if we take time to think about it, it is just the opposite: there is a whole world of details and curiosities that we would not suspect at first glance.
We have put together a list of fascinating facts about sleep and what happens during that time.
1. Like old times
It varies from person to person, but there are people who only see dreams in black and white. Why? It’s a generational thing: older people who remember television before it became colorful, dream more often in grayscale than those who are younger. That raises the question, how do modern kids dream? In high definition?
2. The 5 senses
Blind people also dream… but not in the way you’d expect. These people achieve this using the senses they do possess: hearing, smell, touch, and taste. It’s pretty hard to imagine for sighted people, but it makes sense — it’s basically replacing what you don’t have with what you do have. It works like this with those who are blind from birth. People who have lost their sight at some point throughout their lives do dream with sight.
3. Animal instinct
Maybe you’ve always sensed it, but in this aspect it seems that we are not very different from animals after all, since, like you, they are capable of dreaming. At least that’s the theory: Scientists can’t claim it with 100% accuracy, but some species’ sleep phases are the same as humans. So there’s a basis to think that perhaps your dog or your cat also has a very entertaining life when they are asleep.
4. Battery for creativity
The brain is still highly active during sleep. In fact, great minds have obtained inspiration in their sleep; former Beatles band member Paul McCartney composed Yesterday (one of the group’s biggest hits) in a dream. So, beware: pay attention to the fact that your million dollar idea might be right there in your dreams!
