Mate, a hovering light over a cornfield is basically the universe sending you a personalised invitation to have a complete meltdown, and honestly I respect it.
Did you manage to get any photos? I've been trying to get into paranormal photography here in Norway and the one time anything remotely weird happened near my place I fumbled my phone like an absolute clown and got a blurry shot of my own thumb.
What did it look like up close? Lights, shape, sound? The "can't stop thinking about it" part is actually really telling to me - people who see something genuinely strange all say that, like it gets stuck in your head in a way that a normal thing just doesn't. Would love to hear more details if your up for sharing them.
