Aphantasia and sleep (lemmy.world)

Hi all. I'm interested to know how many of us have a serious sleep issue. So far I haven't found much of a unifying thread between aphantasics, other than that we're very familiar with what the back of our eyelids look like! But one common thing I have heard over the years is a sleep issue.

I have chronic insomnia. Interested to hear back from others.

i wish i could turn off the sound of the world lol

When I found out about how noise cancellation works (a soundwave with an exact-inverse copy played against itself cancels to nothing), it made me think... COULD we turn off the sound of the world? Would it ever be possible to have devices on the outside of a room, sending info at lightspeed, with a device inside the room beaming inverse sound waves to what it expects will reach your ears?
