Time line - losing ones sense of time
I remember in a nostalgic way when Mum was fixated with watches. Every watch we got her she broke within days. It either got wet. Or she fiddled with knobs until it just died of confusion. I would think we bought close on 20 watches two years ago.
Within two days she would come and tell my husband (an old watch and clock fanatic and fixer) that something must be wrong as it isn't working. We believed her, In retrospect I now believe she was losing her ability to read the time.
Now Mum has lost all interest in clocks and watches. When her alarm clock goes off I know she thinks it is the telephone ringing.To tell the time she either listens to her stomach or looks at the sky.
Mum's world has sadly narrowed down to two times. Bed time with constant monitoring of windows to see if it is 'Up time', and eating time.
I believe the behaviours you are referring to are symptoms of a brain struggling to make sense of time, to use time as a means of making sense of certain events, and it must be so frustrating for them. How scary to inhabit a world where even a clock doesn't work like it used to.
Just some thoughts, BE
