I'm glad to be here

1. I've read Shannon mentioning that projecting an aura requires a lot of energy: so, should I expect the need to eat more in the coming month(s) as a result of that?

All I noticed was that I needed to sleep more, so I would be inclined to say no need to eat more.

2. On the same note, it was said that the brain may need more oxygen, glucose, and/or water to process the new information: how do you guys deal with physiological changes in your body while using subs?

I don't really notice any physiological changes other than needing more sleep.

3. Using subs while also using brainwave entrainment: you guys may be familiar with Centerpointe and the Awakening Prologue program.
Shannon says we shouldn't use that kind of thing for more than four days a week if we're also using subs.
But is it because of the Theta/Delta state those CDs put you in, or is there some kind of conflict in terms of new information coming in?

Dunno this one. Only rule I know is not too much brainwave entrainment in general because your brain will start to shift its patterns too much.

4. Masked subs vs. ultrasonics: I don't understand whether ultrasonics are more powerful and they bring faster results, or it's just that being silent they can be used more easily in different situations (e.g., while sleeping).

I don't think ultrasonics are more powerful, just more situational.

5. Using headphones: I understand it's recommended to use them only while listening to masked subs - but is it simply because you may listen ultrasonics with a too high volume while you sleep? What if I listen the ultrasonic track with headphones, during the day?

Could have same problem of volume too high, but up to you.

6. And what if I listen to the masked subs with headphones, while sleeping? The only problem would be the heahphones falling out of my ears, right?

I use speakers at night to make sure that doesn't happen

7. What is better, headphones or in-ear headphones?

Don't think there's a difference

8. Headphones/speakers range frequency: does it matter only for ultrasonics, or for masked subs as well?
I have a pair of Philips in-ear headphones rated for 12-23,500 Hz.

I think it's ultrasonics only.

6. Can I start listening to a masked sub, pause for a minute (let's say something requires my attention), and then resume it? Or should I start it all over again?

I just resume it
