I have similar episodes sometimes. It's most problematic when I'm running errands, where I just can't remember where the hell I was driving to or where I wanted to go. My passenger will have to remind me to turn left in 2 blocks, but half a block later I've already forgotten. Just driving my jeep is hard enough, never mind remembering where I'm supposed to be going. Everything get kind of stretched out, and there's a hazy light distortion around everything. I have to concentrate really hard on what I'm doing when that starts, and then I just want to get home as quickly as possible. The effort of concentrating during these episodes is just exhausting, and I'll end up crashed out or just a zombie for the rest of the day.
It happens at home, at therapy (when I was in it), at work (when I was still working), in the middle of conversations... basically anywhere, anytime. It's frightening though when it starts and I'm already driving, I feel like I'm DUI and might cause an accident.
Skills help somewhat, not completely. Enough to get me home if I'm out.
