Is it normal: deep routed paranoia over cameras?

My entire life i've had a deep routed paranoia about camerasand been spied on. As a kid I wouldnt even get dressed without been under something like my duvet because of the paranoia that there were cameras in my walls. I finally got over that at 16ish. It came from a show my mum watched about a guy who had been found out to be spying on a women in her own home. I remember a scene of a reconstruction of the event where it showed the close up of an eye peering out of a hole in the wall.
I was about 3 or 4 at the time but ever since and even now I go out of my way not to draw attention to myself. I always feel like someone could be watching me through CCTV and other devices, hell I even think moths and other insects could be some kind of high tech spy drone.
I even used to check the holes in my walls for camera lens.
I've spoken to a few people about my paranoia yet they've all dismissed it.
Is it normal for paranoia to be like this?

I've been known to watch the cameras watching me as if to say ''I know you're watching me''
