A quick reply now and I will give it some further thought fr you, I suffer insomnia and it is the middle of the night here.
There are a number of possible explanations. She thinks she saw him or she actually did or she has a great need at this point in her life to obtain
YOUR attention.
1. She thinks she saw him (and you would believe she didn't, call it a hallucination). In her reality she did see your brother. I suggest you
support her in this. Sure, acknowledge your own beliefs but also acknowledge hers. 100 people can see the same event and come out with 100 versions.
The major point here is that the individuals point of view is as valid to them as yours is to you. Again, be supportive.
2. She actually saw him. To be a trifle blunt, you are jealous! Just acknowledge the emotion and accept it within yourself. Perhaps her life is
terrible at this point in time and she badly needed her intervention. Perhaps your brother, knowing your beliefs is working through her, perhaps you
and your Aunt are close or need to be close. Trying to fathom this scenario is difficult. I would recommend that you "go with the flow." Be
accepting and supportive.
3. Attention seeking. She needs help so provide it without taking over. Hmm, here we go again,

be supportive.
I hope that helps a little. I saw the ghost of my next door neighbor and so did my German Shepperd. I could go into details but suffice to say that
in my reality I KNOW with absolute clarity that there is life after death, due to this one event and the fact that I felt the deaths of both my Father
and my Foster Father, both at a young age. (11 and 13)
So I do not have the misgivings you have. Having been abused as a child by a mob of Penguins (Catholic Nuns) I have no empathy for any Church.
That does not mean that God does not exist. There are no certainties in these areas of belief but the one common denominator in my suggestions is to
provide support for your Aunt. Some faiths, Buddhism comes to mind, believe that the soul recombines for a short time with your previous lives before
taking another turn at the wheel of life. The spirit of your brother could now be existing in a much more aware form with enormousness wisdom.
Suggest you read this reply over a few days to let it sink in. You need to consider it in light of your own reality!
Hope this helps
