Supernatural?

I am not superstitious, but this morning something happened in our dorm room that I cannot explain with any physical knowledge that I know. By the time I went to bed, the room light was off, and the A/C was on; the lights in the bathroom were on too.

About 5:55am this morning, I was woken up, by the sudden turning on of the room light and the simultaneous powering off of the A/C. I woke my roommate up, and told him what happened, and he had no idea why either. The electrometer for the A/C was not working; I tried to switch off the light, but despite that the switch can be moved, however many times I hit the switch, the room light stayed on. My roommate went up to the bathroom, only to discover that all the lights in the bathroom went off as well.

I called my electronic-engineering-major father, but he couldn't explain this. Before I finished my phone call, everything went normal all of a sudden: The A/C turned itself on again, and the room light switched off. The lights in the bathroom were also back to work again. This unnatural event lasted three to five minutes.

Until now I still cannot think of a good explanation for all the linked events. Can anyone help me on this? I think I will report this to the Student Residence Office.
