Is it normal to experience meaningless, yet specific coincidences

I have what I describe as meaningless, yet context-specific coincidences occur around me on a near weakly basis, and although my buddy mocks me when I bring it up, he's been around for some of my 'coincidences' and mocks me less so. There are so many, and yet so few have any actual meaning that I tend to soon forget about them, but here are a few examples:

-I hadn't seen anything Harry Potter-related in ages, and then, a couple of months ago, I decided out of the blue to watch Deathly Hallows Part II. The very next morning, I saw a woman walk past me on campus at university wearing a Deathly Hallows Part II shirt. Maybe people wearing HP shirts is common and I only noticed because I had watched the movie, but the shirt was context-specific down to the 'part' I watched.

-Just last week, I discovered a wack-job on youtube whose youtube name was McHenry Cruiser. I remember thinking that McHenry sounded like an odd name because I had never heard it before. I thought it was 'bro' name someone might choose if they wanted to have a 'bro'-sounding nickname on a site like youtube. Well, the next day I went to the hospital for a cluster of blood vessels that had grown to the surface of my nose and popped, and wouldn't stop bleeding. Behold! While I was being triaged, I noticed that somebody with the last name McHenry had a bed there. I googled the name. Ten or so McHenry's live in the greater area, and only one in my city specifically. Now, I'm willing to concede that McHenry could be a common last name I happened to miss prior to a few nights ago, and as the hospital I went to was just off from a main road that runs through to the next state over, the chance of a McHenry going to a hospital are thus that much more, but come on. Right after I had just learned it was even a last name.

-finally, the death of HR Geiger. It's less specific to the preceding event, but a bizarre coincidence nonetheless. I'm not a fan of the man. A great artist, perhaps, but a very dark mind. I hadn't thought of him or his work in years, save for acknowledging his contribution to the art of Prometheus, a movie I never watched nor intend to. Well, the night before his death, I went to see Jodorowsky's Dune. In the documentary, there was a little bit about HR Geiger's part in designing Jodorowsky's version of the Harkonnens' planet and the fortress, and how the legacy of Geiger's work carried on in other movies. Boom, next day after that, he's dead.

It's always the day after.

What gives?
