Paranormal encounter?????

Holy shi guys, this is what happened- There has been a lot of storms around here lately (nothing abnormal, it's the season of storms) so there has been a lot of power cuts too.

We have an inverter, what it does is, it stores power and uses that power later when there is powercut, so that the electrical appliances work fine for upto 5 or 6 hours.
Unfortunately for us, our inverter broke down on the first storm of the year, that too during night. We were using our mobile phones to roam around. The only source of light were the phones.

In a separate room, my mom was chilling and watching dramas on her phone (yes even after the powercut). I was walking around the house, turning off every switch. Ya'll, even your home seems scary in the dark.

When i reached the room my mother was in, she told me, "Switch off this light for me sweetie, its malfunctioning."

What the fuck?

I looked at the bulb and it was flickering.
How the fuck can it even flicker?
That bulb was broken for quite a while, but the question is, how can it even flicker?? There is literally NO ELECTRICITY, NO POWER SUPPLY, ABSOLUTELY NOTHING, SO HOW CAN IT FLICKER???
And do you know the scariest/creepiest part?? the moment i looked at it, it stopped flickering.

I stood in silence for 4 or 5 secs, processing this. Then i informed my mom of this. DO YOU KNOW WHAT SHE DID?? JUST FUCKING SHRUGG IT OFF LIKE HELLO??? MY FATHER DID THE SAME. I KNOW THAT THEY KNEW IT WAS HAUNTED AF BUT THEY CHOSE TO IGNORE IT TO NOT SCARE THEMSELVES.
