Well the other day I was dreaming I was at my aunt's house. She asked me to turn on the light and I did just that. The light in the room didn't change much, only a bit, but the light bulb was off and it turned on after I flicked the switch. Then I tried turning it off and it wouldn't. Since I had slightly changed light levels and saw the bulb on I just thought it was malfunctioning. Anyways I didn't become lucid. Has anything like this happened to anyone before? I thought changing light levels in a dream... even a little bit... was impossible.
