Nah! - I do it by instinct and in my sleep.

Although this can lead to unfortunate happenings! In the our last cottage, which was 300 years old and crazy, the route from beroom to bathroom went down five steps to a half-landing, then up five steps to the bathroom. The bottom steps on both flights were near enough to each other to step from one to the other without going down right onto the landing.
One night, I had semi-woken up, instead of being fast asleep during my nocturnal visit as usual. I made the mistake of counting steps and miscounted, therefor trying to step from the fourth step onto the other flight. I woke up totally and completely just half-a-second before my face smashed into the opposite top stair, as my feet plummetted towards the half-landing below!
My face was red and my eye was black.
