Can switch lights turn on spontaneously?
I live in lawrence where I go to school during the summer time. My grandparents are living up North in Minnesota to enjoy the rest of summer in their cabin. I'm staying at their house during the duration of my stay. In the past couple months, my friend was at the house by himself doing homework when he heard certain weird noises and even voice from the upstairs having a conversation while he was downstairs doing homework. He said it could have been an illusion. The other night when I got home to my grandparents house I could hear my grandpa's vacuum going off in the tool shed in the basement from outside in the driveway. Nothing has ever happened like that ever. I was kind of nervous because I didn't know if someone got in the house. I looked in the shed and turned out the vacuum still wondering what the hell turned it on. It kind of freaked me out at the same time. A half an hour passes I turn off the main light in my bedroom then lie down while I'm reading my iPhone. I close my eyes for 15 minutes when all the sudden my main lights turn on then another light turns in the room adjacent to it. I get up and run out of the house get in my car and drive to my buddy's girlfriend house where he is staying with her. I tell them the story and they were as freaked out as me. The next day we go investigate and when we go one of the rooms where the lights turn on the light wasn't on anymore, but a different light in the same room was one which wasn't on when I left the night before. Later that night my friends and I go back to the place and sit in the rooms in darkness to see if any lights turn on or if we notice any strange activity. AFter after 45 minutes nothing happened so we left. During the night we drove past the house 3 times to see if any of the lights turned on and none were on. We even checked at 2:00 in the morning when it happened the previous night but there were still no lights on. Tonight my friend drove past the place around 10:00 pm and the lights were on in the same room where we turned the lights back off. Someone tell me if this is a spirit or an electric problem!
