Your brain sometimes changes memories to make them feel better or less painful — so memories are not always 100% real. 

Most people feel anxious if silence lasts more than 4 seconds in a conversation.

If you repeat something again and again (positive or negative), your brain starts believing it. 

The brain can’t truly do multiple tasks at once — it just switches very fast between tasks.

When you are tired, your brain filters less information, so you sometimes feel extra confident (even if wrong). 

Most people are too busy thinking about themselves to notice your mistakes.

Listening to certain music can change your mood, behaviour, and even decisions. 

That’s why you see faces in clouds or shapes in random objects.

A smell can bring back memories more clearly than photos or sounds.

Just imagining pain can activate the same brain areas as real pain.
