I am oddly good at hearing engine noises. If a motor or piece of machinery starts doing something different I usually hear it. I worked in manufacturing and I could usually call out a machine that was about to breakdown. Also when a part has been replaced I usually hear the difference in noise.

I have really annoying hearing. I'm not sure how to fully describe it but my ears are super tuned into sounds. Very often I will be sitting with my wife or somebody else and I am like "do you hear that?" and they are like "wtf are you talking about?" and I have to be like "Shhh... That! Did you hear it?" and they are like "no wtf" and then I'm like "Wait no no... Wait... That! Did you hear it?" and they are like "Wait yeah... How tf did you hear that while we were talking? Were you paying attention?" and I'm like "No, I wasn't because I kept hearing this noise"...

Like... Sometimes people's voices just sound like noises and I can't hear them unless I focus because my ears are listening to the noises around me. It can be really frustrating.

Have you ever been tested for Sensory Processing Disorder

Likely red/green colour blind, less cones but more rods (better resolution, also night vision). Your ancestors may have done night watch in the village or been hunters.

I don't think the shadows at night thing is genetics. Think that's more of a paying attention lol. People say they can't see and that's because they're looking for details and colour. In the dark you're looking for outlines and shadows. I learned this from my flight instructor. But it's a skill more people need to learn. This isn't to say night blindness doesn't exist.

You would hate this goddamn bird outside my window that doesn't shut up from 5:30-10:30 every morning

I think I've read the latter is due to a higher concentration of rods in your eye.
