Dont think your mum is crazy it could be old age or maybe she can really see people just cause you cant see what she can dont mean its not there talk to a doctor if your that worried

It could be dementia-- you need to Validate her. talk to her about it as if its real. for instance if she sees a guy you could ask her what he is doing. it could be just linked to something in her past or someone that she knew. there is a book called the
Validation theory(i think) its really good and helps deal with this kind of thing

I sat back and watched her today (July 7, 2009)... Oh yeah... she's watching SOMETHING, SOMEONE, SOMEONES... but she wasn't too upset about it. I kept reminding her who she was in Jesus Christ and that seemed to reinforce her confidence. I personally believe that the 'Spirit' realm is MORE real that the natural... so God Bless her that she can see Angels, people from her past, future or whatever! She's one step closer to getting where we ALL would like to be!

Peace & Blessings.
