I had that experience and caught it on video when my own mother's spirit came to visit in 2015 (1 1/2 years after she passed). In fact, the dogs saw her and began barking before she started manipulating the lights.
I was working at home on 4-6-15 and sitting in the sun porch off our kitchen. At about 3:30p our three dogs began barking at what appeared to be nothing . I suddenly got a headache indicating that a spirit or ghost was in the room. Then, the lights flickered.on and off several times while the dogs kept barking (they saw my mom) and I knew it was my mother visiting in spirit. I thought enough to grab my cell phone and take a video, showing the light switch and the lights flickering.
