I looked after my mum full time after a stroke. Early last year she became very ill and though not dying was struggling with something the doctors could not quite figure out other than her age.
She started going through spells where she would suddenly turn and look at someone and wave her hands about. Unable to talk because of the stroke years before she just smiled and gestured.
I kept saying nobody was there, but she was shaking her head and indicating there was.
In the end I took a photo with my camera and showed her there was nothing where she was pointing. She just pushed the camera away as if saying, I don't care there is, and kept pointing back and whoever she could see.
Over the next few weeks she got weaker and these visions carried on - not all the time - just an hour or so a day. They calmed her. I brought photos to show her and she took the one of my dad (who died years ago) and I could tell he was who she was seeing.
By the end days on the other side of the bed she was seeing her mum there too, based on the photo she took from me.
Only at that point did they start medicating her and she slipped quickly and quietly away.
I have no doubt she believed she was seeing my dad and her mum over several weeks when not fatally ill or under any meds.
Were they hallucinations? Perhaps.
But they were real to her and on the last day she just fell asleep and drifted quickly away. She was at peace.
So really whatever they were they helped her through this time.
It is hard to watch this happen and not wonder.
