I only listen to the audios morning and after lunch since I still have other activities and obligation up to the evenings.
Yes, during that state, you can use a technique which works best for you. As Buhlmann wrote in his book Adventures out of the Body, I had to be aware when the right vibrations, body signals occur as I fall asleep. In my case, it is usually one leg lifting up as I sleep, then, I say silently “Now, I’m out of the body” once. As my astral body detaches, I say “Now, I’m moving to the door” then “Clarity now!” as I travel. I learned them all from the book. I don’t usually feel the paralyzed state when I have involuntary APs.
