Paranormal Investigator Starter Pack:
One (1) EMF meter that's never read anything but ambient interference. A torch with mysteriously dying batteries. Absolutely conviction that every temperature drop is supernatural. A notebook full of 'evidence' that wouldn't convince a magistrate. At least one near-physical argument about whether that sound was definitely a ghost or possibly settling floorboards. Thermal camera footage that looks like a potato took the picture. Headphones permanently attached to capture 'EVP' that sound like white noise with good intentions. One friend who's 'very sensitive' but never quite explains what they sense. Months of footage that adds up to basically nothing concrete.
What am I missing? Let's compile the ultimate checklist.
