Repressed memories are memories that your brain has tried to forget or keep hidden. It's like your brain is putting the memories away in a box and doesn't want you to think about them. It can be hard to remember these memories because your brain has 'repressed' them. It's like your brain is trying to protect you by not making you think about painful or scary memories. It's like your brain is saying, "It's too hard to think about, don't think about it."
