Though these are really odd experiences. Do they really cause you anxiety or do you just question their validity. I am no expert in any way. I would just think that by your story that you and your sister experienced something together that is represented by the washing machine. It could only be deciphered thru psychotherapy sessions. Maybe growing up your perception of things was different than others. The only way to learn about ourselves is to talk about ourselves with people that can help us connect with answers. We have all the answers inside of ourselves we sometimes need help finding them.   Pat
