So I've been reading about Spring-heeled Jack - the Victorian era cryptid that terrorized London in the 1830s-40s - and it strikes me that we don't really have equivalent modern phenomena. Something about that particular creature caught the public imagination across decades and multiple sightings. Makes you wonder if it was folklore, mass hysteria, an actual unknown creature, or something else entirely.
What's interesting is that most of the sightings happened in autumn and winter when it got dark early and visibility was poor. Perfect conditions for misidentification or the power of suggestion. London in the 1830s was also crowded, chaotic, and prone to panic - very different from now. But I'm wondering if cryptozoological phenomena are actually more common during dark months and we just don't have the documentation we used to.
Has anyone else noticed seasonal patterns in paranormal/cryptozoological activity? Or am I pattern-matching where there's no pattern?
