Amazon has a number of mood... romantic fireplaces, aquarium and "sleep" segments. Some run for hours for dozing off naps.
In search, look for "aquarium", "box fan", "rotary fan", "candles", "fireplace", "oceans", "birds"... and like that.
Now... one I'd like to specially recommend... "Loons"... a superb video that has incredibly great photography, and a full history and life stream of what is arguably the most popular subject of bird lovers. As a self appointed "expert" on loons, I learned a great deal. Brings back wonderful memories of canoe trips on the Boundary Waters, and Adirondak Lakes.
The other excellent video, is "hummingbirds". For anyone who has enjoyed this tiny critter, an absolute "must". Didja know that a hummingbird flaps his wings from 30 to 50 times per second?... or that his heart beats 1000+ times in a minute?... or that some fly 500 miles without rest all the way across the Gulf of Mexico?
All of the above are available on "Prime".
