A thoughtform is a headmate whom the host (or another headmate) created intentionally. A thoughtform may very well be nothing at all like their creator, and does not necessarily see themself as a version of their creator, nor as truly sharing their creator's body, nor as having split from their creator. Thoughtforms and their creators usually have very good internal communication.
