you might want to check with her to see if she's able to stay put without going out, and if not you should encourage her to get back to being herself and staying that way or she could go full retard from what is going on with her.
also you might want to check if it's really her doing it or other people/beings, maybe get her to look in a mirror when she souljourns out. And there is also a chance that theres some devious things going on behind the sceens out there that could corrupt her, because as it's supernatural and spiritual, it's not a genuine mortal gift to do so under normal human conditions, and occurs through things like brain trauma. Also she may be playing around instead of using her spirit for what it is menat to be doing, as in her own life, so if she is operating a spiritual gift meant to be bestowed after she has passed away, the oportunity to use this will have been wasted playing psychic games.
There is always some hang time, but that can be a misconception due to inability to comprehend what the gift is really for.
Spirits can help fix lifes problems that occurand have properties for doing so according to right and wrong and making things straight before passing away
also a spirit can be used to notify the senses of your own body to keep you safew and intact. There is a danger that when distracted and away there could be something pressing that needed attention.
And the spirits run on timewarps so her spirit can be there for her and away playing around at the same time like multiple copies, yet they end up having to go back together and thre are paradoxes of the timewarps. There is also the mental fatigue and stress caused from the compilation and compounding of the thought and other sensory input coming back into her unit and causing confusion and mental instability, when theres too many spirits and too much noise and too much memory of action. Then if theres slices and or confrontations in the spirit world there will be things cut short and restarted and it will get skewerd and shredded up and begin to make no sense
there is also the possibility of an impending trap that will cause multiple copies of the spirit to undergo deaths.
she could also mistakenly track things that are not totally in reality and find herself posessed of her actions that do not function here like she is trying to have them perform, things like your spirit passing through objects, flying ect. like the guys wife in inception. which is also a problem, getting stuck in an alternate reality and losing your own sense of how to function in the real physical

theres more to it, but if shes happy and alive and not suffering ill effects then I guess there is not much problem and you should be honored to be in her presence.
