When i was young, I learnt about these mini dolls that dressed like average people and you can tell secrets to, It was said to relieve stress by saying it out loud to "somebody". Some people would get more than one because they would feel "sorry" that one doll has to keep so many secrets. I tried to look for them all over the internet but I couldn't find anything close to them. I think they might be a Native American thing but I'm unsure. My mind just can't seem to remember the exact name.
