Back in 2010, my parents were living with me until they could find a place of their own. I was selling my house at the time and, unfortunately, my dad passed away so my mom and I got an apartment together. It was a cute 2 bedroom/2 bath and had a laundry room off the kitchen.
About a month after moving in, my mom went away for the weekend and I had the place to myself. I was doing laundry and when I went to switch it I noticed my mom's lamp was on. I wasn't 100% sure it wasn't on earlier because it was still light outside. This lamp was a touch lamp and I've heard they can be fickle. I turned it off and checked to make sure the bulb was tight and went on with laundry.
Later, when I went back to switch laundry the lamp was on again! This time I was a bit unnerved but turned it off and went on with my evening. It didn't turn on again that night and I checked the next day when I woke up.
When mom got home I nonchalantly asked her if she'd had any trouble with the lamp in her room and she said no. I didn't make a big deal about it because she would've scoffed at me.
Another month goes by and my mom goes away for the weekend. I'm at home doing laundry and it happens again! Just like the last time. It totally gave me chill bumps and I really wanted to believe it was my dad saying hello. He died suddenly and we didn't get to say goodbye.
On a side note to this story, I didn't automatically think this was paranormal because it could be explained since the lamp was a touch one so I asked my brother in law, who is a master electrician, to inspect the lamp and the outlet it was plugged into. He did not find anything wrong at all and I never had any more trouble with that lamp.
A few months later, my mom moved out and my son moved in. She left that lamp and it was in my son's room. One morning I woke up to find the lamp sitting on the dining room table. My son explained it had turned on in the middle of the night and he didn't want it in his room. Lol
Not sure where that lamp ended up but I honestly don't feel it was a coincidence. I really want to believe it was my dad letting me know he was around.
