I can turn lights on and off just fine.


One thing that does seem to be true though, is that light switches don't work well, if at all in dreams.

In a lucid dream last week, I turned a light switch on, completely expecting it to work (as I was didn't believe light switches not working was actually true), but to my great surprise, it didn't. I tried it several times, then gave up and made the light turn on by thinking it on.

I really was very surprised about it, because I actually believed it would work, but it didn't. Even with me (lucidly) thinking, "Huh, why isn't it working".
