Drone

Have you felt like someone was following you and when you turned around nobody was there, but you were worried they were still behind you? Wherever you turned, your unseen stalker always managed to keep just out of sight?

I bring this up because for several months I've been followed by a constant humming, a droning I can't shake. Almost like tinnitus but it's coming from behind me, even though there's nothing there.

Except it turns out I really am being followed by a surveillance drone. We all are these days.

So the good news is I'm not going crazy.
