Just because I, too, wondered about things as a kid…

Alain de Botton explores why we have dreams:

“Most of the time, you feel in charge of your own mind. You want to play with some Legos? Your brain is there to make it happen. You fancy reading a book? You can put the letters together and watch characters emerge in your imagination.

But at night, strange stuff happens. While you’re in bed, your mind puts on the weirdest, most amazing and sometimes scariest shows.

In the olden days, people believed that our dreams were full of clues about the future. Nowadays, we tend to think that dreams are a way for the mind to rearrange and tidy itself up after the activities of the day.

Why are dreams sometimes scary? During the day, things may happen that frighten us, but we are so busy we don’t have time to think properly about them. At night, while we are sleeping safely, we can give those fears a run around. Or maybe something you did during the day was lovely but you were in a hurry and didn’t give it time. It may pop up in a dream. In dreams, you go back over things you missed, repair what got damaged, make up stories about what you’d love, and explore the fears you normally put to the back of your mind.

Dreams are both more exciting and more frightening than daily life. They’re a sign that our brains are marvellous machines — and that they have powers we don’t often give them credit for, when we’re just using them to do our homework or play a computer game. Dreams show us that we’re not quite the bosses of our own selves.”

Neuroscientist David Eagleman explains why we can’t tickle ourselves:

“To understand why, you need to know more about how your brain works. One of its main tasks is to try to make good guesses about what’s going to happen next. While you’re busy getting on with your life, walking downstairs or eating your breakfast, parts of your brain are always trying to predict the future.

Remember when you first learned how to ride a bicycle? At first, it took a lot of concentration to keep the handlebars steady and push the pedals. But after a while, cycling became easy. Now you’re not aware of the movements you make to keep the bike going. From experience, your brain knows exactly what to expect so your body rides the bike automatically. Your brain is predicting all the movements you need to make.

You only have to think consciously about cycling if something changes — like if there’s a strong wind or you get a flat tire. When something unexpected happens like this, your brain is forced to change its predictions about what will happen next. If it does its job well, you’ll adjust to the strong wind, leaning your body so you don’t fall.

Why is it so important for our brains to predict what will happen next? It helps us make fewer mistakes and can even save our lives.

Because your brain is always predicting your own actions, and how your body will feel as a result, you cannot tickle yourself. Other people can tickle you because they can surprise you. You can’t predict what their tickling actions will be.

And this knowledge leads to an interesting truth: if you build a machine that allows you to move a feather, but the feather moves only after a delay of a second, then you can tickle your- self. The results of your own actions will now surprise you.”

Fascinating! What a marvelous wonder is the human brain, that’s my contribution:)
