I searched in the net and what I got are different parts of brain functioning for this. And I saw something like goes in then opposite but I don’t understand any of it.
In: Biology
* Your memories are not like computer files they are more like a series of “clues”: your five senses and emotions factor into memories
* A theory about sleep and dreams is that (among other things) it’s memory consolidation. Your brain organizes memories while you sleep – one correlation is that people who learn new things in a classroom or formal training report lots of dreams when they sleep.
* Some memories fade or become disjointed because they are not used. That person from your teen years that interacted with -a lot – is now “the dude with the shirt” because the memories weren’t used, or weren’t used that much.
* You can recover some of that, so when the “the dude with the shirt” send you a FB request, your brain will try to get as much as it can – but will fill in the blanks with new information.
The key takeaway is that memory isn’t like a DVD or a photograph – it’s a living thing that can be replenished or “die” based on how it’s used.
