through yume nikki……….
I'm pretty sure OP was reffering to how people actually found the event in the first place.
I mean, there's a 1 in 64 chance that the event will occur, and even then, its not like someone just compulsively decided to turn off the lights and they triggered the event in one try. People open up the game and look at the events. Its a pretty common thing.
Did you count them? Did you exit the room before flipping the switch again?
I didn't know about there was an event like this, because I finished Yume Nikki w/o a walkthrough (only guide that I did myself was by knowing that there's 2 effects found per door)
I got into Poniko's house, only to find nothing to do but switch the lights and kill her. But I decided to return and re-examine the house, so I'll switch the lights again and kill Poniko next but…
Yeah, I got to see Uboa on second try. What's up with that 1/64 thing?
