Not really. You might sometimes be able to guess what someone is doing
e.g. if there is a lot of visual activation, it's reasonable to think they might
be looking at something, but that's a long way from what you're saying.

Again not so. You can usually tell if someone is asleep or awake, and of
course you can see abnormalities like seizure activity or encephalopathic
states, but that's a long way from knowing what "state of mind" someone is
in.

Lately it seems there is even more misinformation than usual in this group.
