Hi Ash, sorry to hear your mum has been so ill, but as the others have said, it is a slow road to recovery and from what you have posted it seems like she is improving. Hope your Dad gets better soon.
I had quite a lot of visitors once I was out of intensive care, I would open my eyes and see my son and daughter, then I would open my eyes again and my best friend would be there! It was confusing but comforting
Take care of yourself
