Have you ever had a dream in which you wake up and go about your daily routine – only to discover that you are actually still asleep? This can be incredibly frustrating as you realize you need to re-do everything you have already done (in the dream). It is extremely realistic and most people experience it. This event is called a “false awakening” or a “dream within a dream”. It is even possible to have multiple cases of false awakenings in one dream. This is used to good effect (though perhaps it is a bit cliched now) in movies.

Have you ever noticed that when you have a bowl of nuts, the bigger ones make their way to the top? This event actually has a scientific name: the Brazil Nut Effect. The term refers to the phenomenon in which the largest particles end up on the surface when a granular material containing a mixture of objects of different sizes is shaken.
