I'm also the host of my system and I use the term "frontlocked"--I can't really leave front/co-consciousness. I only see the headspace in bits and flashes, so I don't know how to help you get back there, but I do have tips on communication. For us, the best way is to record it somewhere, like, we write notes to each other on the sides of my school work or essentially "text" each other on my phone

^ I do that same thing. I have a personal Discord server that I use to communicate with everyone
