A bit weird, a light in my room that hasn't been working just started working again.

I have two night lights in my room, the bulb on one of them has been dead for maybe the past couple weeks or so and I haven't felt like changing it. But just noticed that both of them are now on, I plugged the cord for the lights in earlier tonight but I just now noticed that the one that has been dead is also on. I did move both of the lights off the window sill today to clean it but all I did was move them off and then put them back on it. Dont know if it actually means something weird but something weird involving a light happened to my mom maybe a couple weeks ago too. I thought it was a side effect to the new medicine she was taking but she said she woke up in the middle of the night and the light in her bathroom was on. The light hasnt been working for the past few months but she said she went into the bathroom and was able to turn it off and then on again. But the next morning after she woke up it wasn't working again and hasn't been since I know of since then. Anyone experience something similar?
