So, sometimes the light switches work – that's interesting. Thank you for sharing your experience :-)
I guess, malfunctioning light switches are not a natural limitation of dreams then. It's still strange that so many people seem to have problems with them (myself included).

I really doubt that, Hitokage. If that was the case, the light switches should work in non-lucid dreams, right? Besides, I had the light switch problem way before I even knew what lucid dreaming was. So, there must be another explanation.

That sounds very plausible to me. I never tried to do math in my dreams, but I bet I'd have problems with that, too

The light-switch thing really bugged me, and so I spent some time searching the internet. I actually found some research done on the subject:

Hearne (1981 & 1982) reported what he called the light-switch phenomenon, where light switches and other electrical components fail to work when switched on/off in dreams. He suggested that there may be a limitation on adjusting the brightness level in a dream. Moss (1989), however found that lights could be turned on (so that the brightness level of the room increased significantly) if both the switch and light were in view at the same time. This result was verified by the author. Moss suggested that if only the switch was in view, the action was vulnerable to failure.

I like the idea of keeping the switch and the light in view while trying to switch it on. Maybe it'll do the trick
