my DB was in hospital several times in the 70s/80s due to severe asthma and apparently almost died twice. I recall being with him when he was about 4 or 5 I think on one of these occasions and it was terrifying, we were in the A&E resusication room But my brother and I used to share a bedroom and used to joke about "spheres/balls of light" - to be fair I always played along with it and don't think I ever saw them. He always heard stuff though, he's sort of elaborated but as we thought it was the asthmatic medication causing him to hallucinate (the meds were a lot stronger then) then thought that was that.
However, also as a child but don't think we ever smelled it, my mum and stepdad would strongly smell flowers - I think like roses, in certain parts of the house (old Victorian house), my mum didn't wear perfume then (or rarely and it wasn't this) and we rarely had flowers in the house either. Later my stepdad found delicate coloured drawings of flowers in the attic from Victorian/Edwardian times and we found out 2 sisters had lived in the house at one point so must've been theirs. The smell isn't there now (parents still live in the house) and disappeared as my brother got older, maybe it was like a Guardian angel from one of them over my brother?
Another story, my grandad (mum's DF) was from Luxembourg and was brought up in castles in Germany as his DF worked for a member of the aristocracy. Anyway grandad one day said he'd seen an old man dressed in old clothes, hat etc and mentioned it to his father etc. the people in the castle looked at each other and said "he's (Count someone I think it was) walking again". Eg ghost was walking.... But his description of the man was apparently spot on, I suppose he could have seen paintings or photographs though.
