Our brain has two places where memories are stored – one is temporary and another is permanent. So everyday things like the food you eat, dress you wear,etc. are stored in the temporary compartment.

The Short Answer

Our brain has two places where memories are stored – one is temporary and another is permanent. So everyday things like the food you eat, dress you wear,etc. are stored in the temporary compartment. Other things that happen during the day – like you getting your first car,etc. too are stored in this unit. When you sleep at night, our brain sifts through the temporary folder and finds out things that are important and need to go to the permanent folder. So the food you eat is trivial, but your first car is important and gets into the permanent compartment.
