In dreams, light switches don’t work

I don’t know why they don’t work, but last night for about the 100th or 1,000th time I was reminded that light switches don’t work in dreams.

We were hoping to see the northern lights here last night, so I was intentionally sleeping lightly, waking up every half hour or so. In one dream I looked out my bedroom windows, saw the lights, went out of the room to tell others that we could see the northern lights, tried to turn on a light switch, and it didn’t work. So I tried turning on other light switches, they didn’t work, and then I thought, “Gosh darn it, I’m asleep,” and I woke myself up.
