This Is what I tend to do. I think of what I’ve done so far that day, people I’ve met, I look at my surroundings etc to find odd stuff. I think it does me as good as counting fingers etc. The point is simply to ask yourself if you’re dreaming or not.
Yes but, try to honestly consider the possibility that you might be dreaming and then prove that you are/are not. Remember you want to do this a lot throughout the day. At least 20-30 times a day.
At school i do weird RCs all the time. Nobody cares, i never thought other LDers would care either hehe.
But the nose RC has worked 2/2 = 100% of the time for me. 
Wear a digital watch, and look at it as an RC.
