I have no clue what's causing this, therefore I didn't know where else to post it.

We have those lights that display a green man if it's okay for you to cross the road, and a red man if you have to wait. I (usually) never cross the road if there's a red man, not even when there are no cars around. I (usually) always wait for the green man.

Yet within the last few months, not only once, but twice I've gotten so lost in thoughts that I have simply walked straight out in traffic when there was a red man. The first time, it went fine because there were no cars around anyway. But the second time, I almost got hit by a car, and that car almost got hit by the car behind it, and so on.

When I get lost in thoughts, it's like time stops and I'm just floating around, thinking about whatever. It used to only happen when I was alone, for example while brushing my teeth or cooking (one of the reasons I never use the oven anymore).

Maybe it's normal to just walk out into traffic like that sometimes, but it's not normal for me. I had never done that before. I'm worried that I'm going to get hit by a car or cause a car to crash.

What can I do about it? I don't notice that it's happening before it's too late. For example when I brush my teeth and I get lost in thoughts, I don't notice before I look at the clock and see that it has been an hour or two already (and it feels like my mouth is on fire).
