AP mental projection state... seeking advice :)

[Dominion]

So I'm slightly confused about this, I've read lots and lots about AP (Astral Projection). I've read that one should be focused when trying to AP. I'm always extremely focused when I try it. However at the same time I read your brain is supposed to be in the low Hz range, typically Delta to Theta (as would be the recommended binaural beats) which would get quite near a sleep state.

So I'm not exactly sure how focused + Delta-Theta mental state fit together. Am I looking at this wrong?

I've projected once and it was right after waking up. I'm still trying to figure it out though. Am I too alert?

Some people say they project on caffeine so that seems like it would be much above the Delta-Theta Hz.

Thank you for clearing this up -->:-()>
