I was awoken one night to a loud crash in my bathroom. I went in and all of the things on my sink top were in the middle of the floor. I mean, about 3 ft away from the sink. Everything. Not just one thing fell over and knocked the other into the sink, but toothbrush, toothpaste, hairgel, face wash, e4, handsoap... All on the floor in the middle of the bathroom.
What was even worse is that, between waking up and going to check out the bathroom, as I crossed the landing back to my room I noticed a light had come on downstairs. I went down and both the hall light and living room light were on, except none of the light switches were in the 'on' position. I had to click the switch on/off to make them switch off.
I was living on my own at the time and it freaked me out a little bit, but I'm still in the same house and have had no other experiences.
I should add that, the first thing I assumed was a break in, or in the case of the bathroom stuff, wind. However, all the doors were still locked and bolted from the inside, and no windows were open (not to mention the bathroom is bulkhead bathroom and has no windows anyway).
