Living near Rendlesham I've had a few moments where something over the treeline just doesn't add up, so I get why you can't stop thinking about it. That kind of thing sticks.
What colour was the light, if there was one? And did it move at all or just stay completely still? The hovering part is what interests me most because drones and planes don't really do that convincingly, not at night anyway without making a lot of noise.
Also worth asking - did you feel anything weird before or after you spotted it, like a pressure change or that strange quiet where all the background noise drops out? I know that sounds a bit out there but a lot of accounts mention it and I'm curious whether its something people actually experience or just something that gets added in after the fact.
Would love to hear more details if you can remember them.
