You’re correct on all of those. Including whatever helps you give off High intense emotions, anger ( if you’ve ever had weird things happen around you when you were angry or felt whatever intense emotions you did) , lust ( where sex magic comes in) , fear
The ways you mentioned are the key ways I know to actively manipulate this energy. Energy working martial arts exercises help too, the true techniques employed in these that emphasize the energy around you. They combine with meditation to help you manipulate this energy.
Some places that are often referred to as haunted have this energy stored in there as it’s collected over time from the intense emotions and fear of the people that have interacted with them.
That’s why you hear spiritually attuned people say that the air around that area feels heavy and they have trouble breathing. Etheric energy is very dense and can be overbearing if it keeps being collected into a place .
It makes it easy for spirits to easy manifest themselves through that etheric ectoplasm.
