I wouldn't count on it. It might work, but it seems to me that it would be to unpredictable of a Reality Check (in dreams of course). The scenery might change or it might not. Besides there are tons of other checks you can do that are just as easy, such as checking your watch a couple times or text. Works for me.
Closing your eyes might work. Especially if you try to imagine that when you open them such and such will be there in front of you. This is not a sure fire method though.
I usually do multiple reality checks just to be sure. I start with the watch method, checking it three times and moving my arm as I look at it. Then If there is some text handy, I read the first couple of lines twice and check for any instability in the overall text.
You can also do "how did I get here?". Try to think back for as far as you can and see if there are any gaps in your memory.
Or you can look at your clothes and see if they are your own and if they make sense (clown suit? its a dream).
or you can atempt to fly (better not do this one in public), jump up and attempt to stay in the air. or visualise your self floating up slowly.
It can also help if you make sure that any of the information you are using (watch, text, whatever)fits in context. Is your watch displaying sattelite coordinates? (probably a dream) Is the text on the back of a CD a recipe for making a nuclear bomb?(again, probably a dream)
The most important thing about reality checks is that you really question your situation. Don't just glance at your watch a few times and not really believe you could be dreaming. Be really critical of your surroundings.
Critical thinking and attention to details during a reality check really pays off. This training allows you to re-awaken the ctitical part of your brain during the dream.
