That's a bit alarming, actually. What I think you should do is to get a device such as this: https://www.homedepot.com/p/Gardner-Bender-Outlet-and-GFCI-Tester-GFI-3501/202867890 that works for your location's mains voltage and plug setup (if you're outside of North America) and then check your outlets to see if something's miswired. What you're describing certainly doesn't sound normal at this point, so I think that suspecting your AC circuits might be a logical next step.
