Poltergeist. Russia

I.P. Gurinova writes to the Commission on:

One day (1987-1990) I was alone at home late at night (my husband worked the night shift). it was a little scary, I couldn't sleep and lay with my eyes open, looking at the full moon in the window of the opposite room. The lights were off everywhere. suddenly in the next room ... The lights came on! I got out of bed, went into that room and turned off the light. The switch was a key with a corner in the middle and a light touch was enough to make it work. Could he have done it on his own or did "someone" help him?! I don't know if it's important, but there was a picture of my husband's grandparents on the wall in that room. The apartment was located in a house on Comradely Avenue.
