Marydoll my mother had a very similar episode. She thought the flickering tv in the cubicle next to her (hospital) was someone setting g the ward on fire - every night she feared they would all die.
Then deliveries were made below her level and she thought illegal immigrants were being smuggled into the hospital to work as nurses - who of course she didn't trust. She started to pull her lines out of her arms, to allow her to escape at night.
I stayed overnight sleeping in a chair for the week or more she was there.
But she thought I was 'their' spy, so was very difficult with me.
silentgames ... I do agree with your understanding of the situation, it is not their fault it is the illness. So hard to deal with though isnt it?
apple trees not flowering this year. Anyone else?
Lack of public toilets in towns.
