Does this one mean something to you?
A Testimonial: From childhood my dreams were all in a theme of inescapable out-of-control situations: anxiety. Just after the recent intensive, while waking up one morning, that knowledge came to me, Ah I know, and instantly that lifelong anxiety disappeared. Poof! Complete relief. Then, gratitude. A month later, still no anxiety in dreams that I can remember. So yes, an intensive is worth it.
(Note 9/29/2019: anxiety in dreams is identifiable but usually not inescapable since this note was written. Now the suffering when it appears is a layer deeper; the dream situations are more constructive and less dramatically and obviously anxiety-ridden; I seem to recognize myself suffering, recognize it is not my dream story making me suffer, wake up enough to drink some water and have an aspirin, and vow again to eat no simple sugars the next day, which strongly predict my insomnia, night-time headaches and anxiety, and nightmares. So yes, there was a real and significant emotional step forward documented here.)
