TIL before CT and MRI’s were available, doctors used to replace the fluid in and around the brain with air to do imaging with X-rays. (en.wikipedia.org)

Apparently this was done because air captures less X-rays than CSF and thus creates more contrast with brain tissue compared to the cerebrospinal fluid.

Unfortunately this was pretty painful and uncomfortable.

You literally just described how I would sleep growing up. Find a small crevasse (usually behind the couch or under a bed), wiggle myself into it and fall asleep. lol

When headphones became cheaper, they were added to the mix too. 12 people in a house gets pretty loud! Or when my dad had to do rock concerts. He’d help me find a place to hunker down in.

I think a really key difference is that you could make yourself comfy in your little nook, and you could leave it at anytime. Plus in your case it sounds like you went there to escape the noise. This place is the noise. Even if you have a full on panic attack, you physically can’t get out of that tube without the techs pulling you out. Having the choice and ability to leave a space is really important.
