After reading about ADA and thinking a lot about it, something struck me, maybe it's silly...
ADA is about being constantly aware that we are in the real world, by noticing details around us and sensations. Most elderly people have conditions like back pain, that hurt them all day long, that should qualify as ADA, right? When your back hurts you can't think about anything else...
I asked my grandmother if she felt her back pain inside her dreams, she had a hard time answering but she finally said "I guess not...", but she hasn't had any lucid dreams.

Is it just that these people aren't aware that they can have lucid dreams, and are not trying?
