Finally, I feel I have made progress going under. I felt like I have been 10 times lower then ever before during a session.
As some of you may remember, I am real hard to hypnotize, so if there anyone else having troubles like me then I suggest you listen to Esuccubus - Night, Night Induction each session for a while, then switch to the Night Night Trigger file. The trigger file worked the first try and put me this deep. It's worth a try.
