Extreme Paranoia Question

I know that paranoia is incredibly common in OCD as is, but I was curious: does anybody else experience really heightened days where you get insanely paranoid about things like a phone call from a random number, or a sudden knock at your door? I pick up calls even when they are suggested to be spam or scam callers. My brain convinces me that I am getting a life-altering and catastrophic call, or that somebody who wants to harm me is at my door. This may included paranoia of being taken away by the cops and imprisoned, or by a mental health professional due to my real-events. Even anxiety about the possibility that somebody has arrived to give me bad news about family or friends.

I am curious who else relates to this? It would be comforting to hear that I am not alone by seeing other peoples experiences and paranoia on these issues.
