Appeasing hostility

This pertains to one of the stronger instances of UPG I have had, which involves a very negative experience. This happened a few years ago, and was the singular instance where I have experienced a distinct urge to run and not look back. A bit of background info then. I have always been fairly comfortable around the dead, be it at a funeral or in a cemetery; one of the reasons I have chosen the career I am in us because of my level of comfort. I rather enjoy cemeteries actually, and there are quite a few nice ones scattered around the city I live in. Often times my fiance and I will drive to one and walk around, especially the ones who have older monuments. The long and short of it is that I have never been uncomfortable in a cemetery; never found it weird or creepy.

Now, a few years back I was visiting a mausoleum with my fiance, her uncle had a vault in it, and I was doing perfectly well before we entered. Upon entering the structure however, I became increasingly apprehensive. We climbed the stairs to get to the second floor and I became very uncomfortable. The longer I remained in the building, the more I felt unwelcome, as if some oppressive force was really annoyed with my presence and wanted me to get out. At this point, my fiance had noticed my colour was a little drained and inquired what was wrong. "I need to leave, right now" I replied . "Why?" she asked, "You've never had a problem before". "Something really, really doesn't want me here." I responded, and the feeling was only getting worse. It was at this point that I remembered an article I had read, which was written by a couple of Celtic Recons, appropriately titled: "KILLYOUANDEATYOU: or a well intentioned Celt's guide to non-Celtic bio-regions". At this point, it certainly felt like something wanted to do just that, and I walked as calmly as I could out of the building, and did not stop until he feeling had subsided. Fortunately it did so almost as soon as I was past the threshold. I have not been back to that building since. It was a markedly odd event, but one which makes no sense to me except through the lens of UPG.

And now, my dilemma. This particular mausoleum is fairly new and frequented by an almost exclusively Catholic clientele.  The funeral home I will be working for, is fairly close to it, and is also almost exclusively Catholic's who often favour entombment. Therefore it is exceedingly likely that in the near future I will have to go back to this mausoleum. I am then in need of some method of appeasing or reaching some sort of understanding with the spirit(s) of place, and I am at a loss as to how to go about doing this. It is publicly accessible, so I could fairly easily get in and try to leave an offering, though I am then at a loss with regards to what I should leave. It would be rather helpful if anyone had some suggestions or sources they could direct me to. I've gone through the article I mentioned above, but unfortunately I am (likely) not going to be in a position where leaving "well enough alone" is a possibility open to me.

Gorm.

PS: I wonder if perhaps posting this on the GN mailing list may also elicit some suggestions from those who do not read my blog?
