Choose a day, wake up, and spend listening to the same file until night.

I think I tried it, but at some point, I just become too awake, because hypnosis and sleep are very close for me. Doing self hypnosis is like a nap.

But I was wondering if people have trained themselves to go into trance faster this way?

Personally, I don't think it would work. You'd probably end up tired AND bored of this file, which could make you unable to get into trance.

Unless it's subliminals, you'd develop a resistance to the file, as your mind would habituate, or ignore the stimulus after a while.
