A low hum in Denmark, Horsens
Low hum, sounds like some kind of machine or industri noise from far away, yet it feels like it is physically nearby. Comparable to the sound of large air mass rushing through some kind of large cavernous Space Would like the ability to add notes in the future

Write it down while you still remember the details. We will look for the others.
If this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
