Im sharing a laugh here with myself having not seen the initial post!! lol To Katfish, yes, indeed your control over your brain wave states is all of thee above. If I may ask you to define any current life events that may be keeping the mind a bit more occupied than usual? Are you noticing a difference in your ability to focus in your yoga practice and meditations?
I also want to commend you for exercising your astral body via yoga and pranayama breathing. These are both excellent ways to energize your spiritual organs and astral being.
I would also like to recommend the "Week Four- Chakra Work" meditation to you, as a means of clearing out any disturbances in your being that may be hindering your focus and brainwave states.
Keep us posted here, and thanks for asking what many are also thinking.
Have a blessed new year.
