Immersion

Immersion is the session itself. It is the part people picture when they think about this work, and it is also the part you have least direct control over once it starts. What you can shape is the conditions you bring to it, and the room you do it in.

That is what the research in this pillar keeps pointing at. A study of counselling rooms found that the physical space changed how people rated the person sitting in it and how willing they were to talk. A large prospective study found that what someone brings to a session, their state of mind and their expectations, is associated with how that session goes. And the work behind the standard measure of dissociation matters for a different reason: it gives a plain vocabulary to an experience that unsettles people largely because it is unnamed.

Read together, the honest summary is that conditions matter and outcomes are still not guaranteed. Set and setting are not a lever you pull. They are the ground you stand on, and standing on better ground is worth doing even when nobody can promise what follows.
