This disembodied life has no discriminatory mind. It will tend to go by it’s tendencies. Whatever Karmic substances which is still not dissolved, which will form a certain type of tendency, will drive it in certain directions.
Certain directions means, wherever there is life, and the life is of such a nature, that it breathes minimally. For e.g., a Tamarind tree. If you go and watch other trees, you will see lot of birds will be sitting, for the nights rest. No bird will settle down on a Tamarind tree, because the level of Oxygen around the Tamarind tree is extremely low.
It may also move in the direction of a Yogi, who has a certain mastery over his breath. Because he is not breathing as much as others are breathing.
A Cobra also has a certain influence on this life, simply because it holds it breath for long periods of time.
