This is a really cool list of human reactions or biological phenomena that happen, we are aware of them, but do not know how they came to be.  Here are some examples from the list:

Deja Vu. Ever get that feeling that you’ve been here before? Or remember something happening to you as it actually happens? Like a glitch in the Matrix, it’s as if you saw this scene of your life in a preview, and already knew what was going to happen.

Sleep. In 600 million years of evolution, most animal life on Earth has spent about a third of that time in a completely defenceless state, unaware of their immediate surroundings, not searching for food, or building shelters, or anything else to ensure survival.

Here are another couple on the list, and likely one you are not entirely aware about:

Spontaneous Combustion. Throughout history there have been reports of people suddenly bursting into ultra hot flames for no apparent reason. Their bodies are instantly consumed, leaving only an oily soot as remains, and sometimes a limb that’s untouched by the flames. The immediate area surrounding the person oft en seems remarkably untouched by the heat or flames, which is even more astounding given that the body would have to burn twice as hot as a crematorium to liquify in this way.

Hiccups. Every now and then, something irritates the diaphagm, that area below your lungs that helps you to inhale, and you get the hiccups. They interfere with work, personal life, and sleep patterns, and can eventually push the victim to their limits of endurance. You drink water, hold your breath, stand on your head, and swallow sugar, and pretty soon the spasmodic attacks subside… hopefully

Is your mind blown away and do you have any theories on any of the ones on this list?  Feel free to comment.

And in somewhat of a corollary or opposite yet related topic to the video above, this one get into “the psychology of mystery”.  Wait what?  Yes, this asks the question why do we feel the way we do about mystery.  Why do we repond in a certain fashion and continue with curiosity at times?
