I'm a high school student, and when I come to school in the morning (around 9 AM), I feel OK, and I can perceive everything without a problem. Then, after around 1 PM, I start feeling as if I can see things, but I can't really process them as objects. I don't really know how to explain this, but it feels like my mind is blacked out, and I see things without my mind analyzing them and transferring them to concrete mental concepts.
When I'm in such a state, I would walk in the classroom and not actually have the classroom conceptualized, except for the immediately necessary details which are required, such as where I sit.
Once again, this doesn't happen before around 1 - 1:30 PM, and when it does, the effects of this 'problem' keep increasing exponentially, so that during the final class I'm almost unable to navigate, I feel lost and overwhelmed.
Can anybody else relate? And what do you think could be causing this strange problem?
