Network Disrupted By Unknown Entity

This is the first time I get to post an experience of my own. I have been an active member on this platform for as long as I can remember, reading stories of other users and also commenting on them. What I am about to share occurred last night while I was surfing the Internet with my phone. I live in a two-bedroom flat with my family in a government-owned estate. My estate consists of many blocks which comprises of two or three-bedroom flats. My family chose the ground flat of our block when we were moving in back in 2002. The blocks face each other likewise the flats too and you can walk by anyone's window at any given time especially those living downstairs. I am noting this so you can understand what I'm about to say.

Back to my story, I was up browsing the Internet until it was around 2am, my elder brother was fast asleep beside me, I think it was around 2;15 or so when I heard a noise coming from outside my bedroom window, in my country we have truck-pushers who push around noisy trucks (carts) while trying to get rusted metals and what nots for recycling. The noise this carts make was the exact noise coming from outside my window. It was as if someone or something was pushing a truck (cart) to God knows where, the noise I believed at the time were coming from the wheels like the wheels were about to fall off the truck (cart). I wanted to ignore this, but it was 2am for crying out loud, no truck pusher operates around this time for no reason whatsoever. I tried looking from my window but I was unable to catch a clear glimpse of who or what was passing by, disappointed, I decided to lie down and continue stuffs with my phone.

Then I realized my network was gone like there were no signal bars or anything. I couldn't access anything online for minutes. This has never happened because my network provider is one of the best here in Nigeria and if issues were to arise concerning network availability they would surely notify us, the subscribers. I decided to go urinate and when I came back and saw that the situation with my network/internet was still the same, I decided to sleep feeling disappointed.

Minutes later while I was still trying to get myself to sleep, I heard the same truck (cart) noise coming from the opposite direction where it went to before, it passed my window a little too fast this time around because when I tried looking I could only see a sort of shadow, and the noise continued further away until I could hear it no more. A little disappointed at myself for not being able to see whatever it was, I resumed my position on the bed, then I had this urge to pick up my phone and try accessing the Internet one last time before I give up. Alarmingly, my network was back right after whatever it was had gone back from where it came from. I was damn shocked!

This is really baffling because I can't just put it all down to coincidence. Why was I unable to access the Internet or make calls after the entity passed by? And why did my network become functional right after it passed by again from the opposite direction?

Mind you someone who might have had the intention of perpetrating a crime secretly wouldn't push whatever it was noisily like that at that hour of the night because it would attract unwanted attention! I want to know if someone has experienced something similar to this.

Thanks in anticipation!
