I don't tune into any of them that I'm not related to or aren't from the Gods, unless it's a child or murder victim who needs help or something like that.
This is not a daily occurrence unless it's someone who wishes to speak to me and is escorted by the Gods. Dwelling too much on ghosts and especially Astral entities without a grounded mind produces instability and most people can't distinguish between this and fantasy.
If I go through a graveyard, a hospital or some place of mass slaughter with a lot of death energy, for example, I tune them out or close my Chakras. Not doing this causes more problems than it solves.
