Kid, I think i know the old lady you're referring too - seems to fit description. She lived on my street, up past the plough, until earlier this year when, after a few episodes of night-time wandering in her bedclothes she was taken into a home. Didn't know the full details. I always used to chat with her when I saw her in the street - and she'd often be talking about her trips down to Lordship Lane. Lovely old lady.
