The original discussion from a couple years ago had been closed, so I am starting a new one.
I realize sometimes we will see something that could either be a coincidence or something very real. There were a few "sightings or unusual scents" in the past regarding my late Dad.
Today we had a strange incident with my elderly cat  and his ID collar. How in the world did the cat get on his collar as he now doesn't wear it when inside the house as it is too irritating to his neck at this age. He always waits for either sig other or myself to take the collar off as soon as he comes in from outdoors.
Maybe it's my late Dad once again playing tricks :)
