GreenGran78 - not strange atall - displacement - its a coping mechanism.
I worked in a Hospice for many years and managed my emotions professionally.
Once, after participating in a particularly sad situation I was walking home past a pond. In it was a male duck frantically trying to ‘lift’ his mates head clear of the water ( she was obviously dying/dead.)
I was distraught - and, even now, the memory of those ducks upsets me.
It was, for me, ‘safe’ to let my emotions out over the ducks than over the countless sadnesses I had been involved with with people/families etc over the years where I needed to be clear headed.
