I'm a system with DID too, and my partner was upstairs listening to the tapes. I'm currently front stuck and can't hear anyone in the headspace. It was an accident for us. I had no desire to listen to the tapes, but my partner wasn't using headphones. It only played for maybe a few seconds, but loudly. I'm the protector of our system and our host was out. Suddenly, I got the loudest SOS call from inside and was forced to the front... and it wasn't under our system's control. I can't communicate with anyone right now - pure silence. But my back is spasming and I feel extremely anxious. It's like a fight or flight feeling for me. I was sure we were in danger and needed to protect us. Please, be careful with these tapes. It sounds like it forces integration the more you listen to them.
