Do vacuum cleaners send you to sleep?
Believe it or not, there are quite a few videos on YouTube that are basically just presented so that you can listen to the noise they make, which apparently helps some people fall asleep. Personally, the noise they make grates on my nerves. But if you’re one of those people who finds their constant whining and droning makes you drowsy then check out this one below.
The video is almost 3 hours in duration, so if you haven’t fallen asleep by then I guess you can say it doesn’t work for you!
