I blink every time the car i'm in passes a tree
It's hard to explain. But when for example there's a row of trees by the road, I have to blink when each one passes the dashboard of the car. I only do this when I'm in the front seat. Not driving, or in the backseat. It's not just trees either, it's the white lines on the road and lampposts sometimes too. If I'm listening to the music in the car, it bothers me when the rate of the objects that passes isn't on the same beat as the music (so I don't end up blinking to the beat either.)
I've tried stopping it, but soon I just forget about it and start doing it again, without even noticing.
Do I have OCD???
