So, just now, I felt a weird sort of pressure start from the very center of the crown of my head and sort of radiate through my brain, or head in general. My eyeballs are feeling weird, and can't focus on things like they did a moment ago. Everything is instantly gone a few shades more fuzzy in the vision department.

On top of that, I feel sort of...not as attuned to reality. It's hard to describe, but it feels like I'm having a derealization episode.

Oddly, just as I typed the last few sentences just now, my mind snapped back and the fuzziness is gone. Now everything on my screen is intensely bright, almost blindingly so.

Odd.
