Kitchen Light Turned On and Off by Itself at Night

So anons, I'll tell my story. I was about 15-16 years old, I don't remember exactly.
For some reason I stayed the night at my sister's place back then. She lived near Altufyevo, in a new building, a three-room apartment, I roughly sketched the layout on a diagram. My sister didn't live alone but with her boyfriend, a micro-dog and 2 cats. I went to sleep on the couch in the living room, and in such a way that the hallway was visible (the door to the hallway was one of those sliding ones and I didn't close it). The cats went to sleep with me and the dog was wandering around somewhere. Anyway, I'm scrolling through something on my phone, my sister and her boyfriend went to bed a long time ago, all the lights in the apartment are off.
Then I hear the dog bark a couple of times, run through the hallway from the kitchen somewhere toward my sister's room and go quiet. I didn't pay much attention, but then I see the light in the kitchen turned on. And I even heard the click of the switch. I got so fucking scared it was like I was paralyzed, I'm just staring dumbly into that hallway and don't understand what to do. A couple of minutes later I hear the click of the switch again and the kitchen light goes off. With my pants full of shit I went to my sister and lay down on the floor in their room, tried to explain something to them but they didn't believe me.
