Why does paranormal activity always spike around the autumn equinox?

I've been keeping records for about three years now - every autumn, particularly around the equinox, I get a marked increase in activity. More EVP on my recordings, more cold spots, neighbours report more weird stuff. It's not just me either - I've been chatting with other investigators and they've noticed the same pattern.

Is this just confirmation bias? Or is there actually something astronomical/energy-based happening around the equinoxes and solstices? I'm genuinely curious if there's a scientific explanation that might bridge the gap between paranormal believers and sceptics.

What's everyone else's experience? Do you lot notice seasonal variations in your investigations?

Definitely not just confirmation bias, mate. The equinoxes are when day and night are in perfect balance - there's probably something to the thinning veil idea. I always get more activity around Halloween and the spring equinox. My theory is that these astronomical events create some kind of electromagnetic anomaly that spirits can exploit.

Is this just confirmation bias?

Yes. Absolutely yes. You're more likely to investigate during autumn because of Halloween hype, so you're bound to find more 'activity'. It's basic pattern-seeking behaviour. That said, I don't have evidence it's NOT happening, so crack on with your investigations.

Interesting timing question - I've noticed the real spikes are actually 3-4 days BEFORE the equinox, not on the day itself. Might be worth checking your records more precisely? There could be something about the build-up rather than the event itself.

The autumn equinox coincides with harvest season which meant more gatherings and deaths in medieval times (childbirth complications, accidents, etc). Maybe locations that experienced trauma during autumn just naturally have stronger presences? It's less about astronomy and more about historical trauma patterns.

I've kept records too and honestly I see more activity during the longest nights of winter (late December through January) than the equinoxes. The autumn one does pop up but it's not the biggest spike for me. Maybe it varies by location?
