It's scary when that happens. But like Dej said....."sometimes we can get so stressed, and so head down, and into the wind that we zip by our projects, and tasks, and we look up and we were in remote control".

Have you ever driven somewhere and when you got there thought "I don't remember a thing about driving here". We're so engrossed in our thoughts that it's like the current activities aren't "recorded". Or we're so focused on another event that we don't concentrate on the present.

Sometimes overthinking about it can cause it to get worse. It's hard not to think about when you're worried about it. I'd make a few notes about it.....like the date it happened and what the circumstances were. This way, if it ever happens again, you can refer back to your notes and compare them.
