Never noticed it with poltergeist stuff personally but I've definitely caught more interesting EVP during full moons, which is probably just confirmation bias but still makes you wonder if theres something to the electromagnetic angle people always go on about.
Anyone actually logged dates and moon phases properly over a decent stretch of time? Like months of data not just "it happened twice so it must be true" lol. Would be well interested to see if the numbers actually hold up or if we're all just pattern-matching ourselves into a rabbit hole.
