OSDD-1
Doesn’t everyone have parts?
Kind of. Everyone has modes: work-you, mom’s-house-you, 2am-you. The difference is ownership. Ordinary modes feel like mine, and you can move between them. In OSDD-1, switches happen to you and feel not-me, and a part can hold feelings or memories the rest can’t reach. “Watching myself from behind glass” is a common description.
