It's been a totally random occurance when it's happened, but yes it could certainly be something in my subconscious triggering it. I wonder if I've had more "limited symptom" attacks than I think, since I sometimes feel a little "unreal" in the late afternoon - usually when driving (Why always driving, when it's the worst time? Probably a sensory overload.) But it's about the same time the ADHD stim med is losing effect and that "crash" is similar - tingling skin, fuzzy brain - but the disassociation feeling is the difference. Like I can't feel the steering wheel in my hand, my sight narrows and I have to fully concentrate on just driving. (Again, don't worry, I never have a problem driving when this happens, it's just an unpleasant feeling.)
