My wife and I have a small battery powered speaker on a shelf in our bathroom that we plug our iPods into during showers, baths, cleaning the bathroom, etc. It has suddenly started to turn itself on by itself. This is especially odd as the only way to turn it on is to turn the volume dial on the side. You know, like on the toy walkie talkies we all had as kids? You turn the dial until it clicks on, then turn the dial to raise the volume. It takes a wee bit of force as it meets with some resistance to make that first click.
Last night, around 7 or 8pm, my wife heard a weird hiss or whine coming from the bathroom. I found the source of the notice was the little speaker was turned on and the volume was slightly up. It seemed odd since there was no iPod in the room nor had either of us used the speaker in awhile. We shrugged and turned it off. Click.
My wife called me at work about an hour ago to say she went back into the bathroom and found the speaker was turned on again and the volume was slightly up again around the same level. Neither of us has touched it since last night. She hadn't left the house since we turned it off so it's not a neighbor with a key sneaking in to use our bathroom when we aren't around.
I don't know the mechanics of the power/volume dial so I don't know if there's a fault in the system (from age and usage) that might cause the dial to spontaneously slip. And the dial spins up towards the ceiling so it's not like the cat could step on it while exploring the shelf and accidentally turn it on. And the shelf isn't next to the light switch so it's not a case where we're accidentally turning it on while reaching past it.
Any thoughts or theories besides "Yup, it's a ghost"?
