What's everyone's gateway paranormal case?

Mine was watching a documentary about Borley Rectory in 1997. I was maybe 12, couldn't sleep for a week afterwards, and suddenly I was obsessed with researching every paranormal topic I could get my hands on. The vicar's ghost, the mysterious writing, the general creepiness - it all just clicked with me.

So I'm curious: what was the case that made paranormal investigation feel real to you? Not necessarily the one you believe most strongly, but the one that got you hooked? Could be something famous or something completely obscure. Reckon we've all got one.

Skinwalker Ranch for me, but honestly that was because I watched the podcast while recovering from surgery and was probably high on painkillers. Didn't help that I have a massive dog and kept thinking I saw something moving in my garden. Became genuinely interested after the drugs wore off though.

The Enfield Poltergeist case. Read about it in a book my mate lent me when I was about 15. The level of documentation - photographs, investigator reports, testimony from multiple witnesses including police - made it feel credible in a way most paranormal stories don't. Whether you believe it or not, something genuinely unusual happened in that house.

Honestly, it wasn't a famous case. My nan told me about a ghost in her village church that was apparently documented in parish records going back to the 1600s. Made it feel like these things weren't just tabloid nonsense. Real communities had real experiences.

Loch Ness Monster. Classic gateway case because you can't dismiss it as entirely impossible. Water's deep, habitat is massive, and some strange things actually have been in that loch (giant sturgeon, etc.). It's the perfect entry point because it's not immediately absurd, but it's still fascinating.

The Dyatlov Pass incident. Absolute rabbit hole of a case. Started reading about it and suddenly I was consuming everything about unexplained deaths, Soviet secrets, and wilderness mysteries. It's less about the paranormal specifically and more about genuine unsolved mysteries, which is kind of better.
