/*\ Namaste :-}}
- you said, in part: "there was a square area of coldness that when you moved into it, it visibly chilled the skin."
- if this is in fact a static cold spot (regardless of whether the furnace is running or people come and go in the room) then it may be indicative of something that happened there (likely unpleasant) in the past (maybe before the building was there or when occupied by others)
- if the cold spot goes away when you leave the room then it may more likely be an entity somehow associated with you , as you suggest
- another possibility is that for some reason you (or your friend) have projected some aspect of yourself away from the reiki area (even done so without realizing it) - but I would put this possibility farther down the list for the time being as that sort of "projection" is not common I would say and not done at the drop of a hat, so to speak.
- the idea of smudging is a good one
- hope this helps
