They will visit and such often yes, but they won’t be there 24/7 of every hour of everyday, demons and such aren’t omnipresent. They live their lives, have family, friends, jobs, and so forth. Humans just often feel that once they become intertwined with some beings that the beings give up their lives they had prior to them up which is usually just not how that works.
A lot of being in positions of power are known to send familiars, guides, their underlings, and such to watch over someone or check on them when they are busy. I mean anyone can create constructs even nonhuman beings to help them get things done, but most people view beings as these omnipresent, omnipotent, all seeing, all knowing beings to a point they take on this semi deluded ideology of them and forget these beings have lives long before them and you more or less won’t know the full extent of the stuff they have to deal with in their waking life because people are too focused on the idea that the being becomes theirs and dedicates itself to them every hour of every day.
At some point newbies will have to start wondering is this a thoughtform? is my desires overriding my common sense? why does this being stay with me all day? does it not have other things to do? I honestly feel that people use the omnipresent excuse to help them validate the fact they want to really believe these beings are going to spend all their time with them.
