If I were you I'd get my electrical system checked.

It sounds like odd light bulb behavior to me, but not necessarily metaphysically related.

My house is old and I know the electrical are dodgy as heck. But one specific room in my house had a dimmer light and I watch someone turning the dimmer up and down on a regular basis. If I didn't know better I would have blamed it on the house.

Whoever it is is handy for when I can't be bothered to get up to turn the light up to read. Lol.

Though it does make for some odd impressions when I look at the ceiling and ask for the light to be brightened, and it happens "on its own," and then I say thank you as if it's the most casual thing in the world.

No wonder people think I'm a nutter. :p
