10 Strange Things Your Brain Does Without You Realising

You don't have the same visual acuity for each thing in your environment. Your brain takes in the information you see, and it makes up the missing pieces to form a picture of what you are seeing, which helps to make the world around you seem smoother.

The music that just won't fade from your consciousness is called an earworm. Some tunes, particularly songs that have very popular beats, can end up being mind-numbingly repetitive, even if they're not playing.

In a frightening or very stressful moment, it may seem like time has passed more slowly than actually has. This can be associated with heightened attention and recall of extreme experiences, but not necessarily with actually slowing down time.

Faces are important social cues and human brains are very efficient at processing faces. Names, though, are frequently random identifiers that must be associated with another memory, which is easier to lose.

Sleep is not just the time when your brain turns off. It helps consolidate memory, learning and other vital functions when your body is at rest.

Your expectations can change the way you feel, such as how you feel when you are in pain or discomfort. That's why what you expect and factors like past experiences can shape your reactions to a situation.

There is no perfect record of memory. Your brain reconstructs your experience when you remember it, and details can modify with subsequent information, feelings and retelling.

Individuals tend to focus more on negative things and threats than equally strong positive things and threats. This was known as negativity bias and can impact the way you see everyday scenarios.

Sometimes you may feel someone is looking at you but you are not able to see them clearly, as you may be noticing some peripheral movement or changes around you. But the feeling doesn't necessarily mean that someone is watching you.
