Subjective effects.

Subjective effects	Definitions	Patient perspective
Oceanic boundlessness	Oneness with the universe accompanied by a sense of awe	“I had these moments of insight that were very profound. Everything would come together all at once: fear, beauty, wonder. Sometimes they would ebb and flow during a session too. It was spiritual in a way. I felt enlightened.”
Ego dissolution	Complete loss of subjective self-identity	“Once I started dissociating, I detached from who I was and everything around me. I just dissolved into nothingness. It was dark and very uncomfortable at times.”
Emotional breakthrough	Categorical leap in affective experience	“I had my biggest breakthrough after session six. I was able to connect with my younger self and tell her that this [trauma] wasn't her fault. That she did the best she could. It was an emotional purging. After that, I started seeing everything in a new light, and started forgiving and accepting myself and past experiences. That's when my healing truly began.”

In response to treatment, the patient reported changes in three facets of mysticism: Oceanic boundlessness, ego dissolution, and emotional breakthrough.
