I can fall asleep almost anywhere. I routinely fall asleep in the break room at work. Once, I was helping a friend fix his car, and I fell asleep on his garage floor when he went inside to get water.
But in a hot metal tube tearing through the sky, with my neck all kinked? Get out of here, man.
So I actually have a lot of trouble sleeping, and have restless legs and periodic limb movement disorder. I also have pretty bad diagnosed ADHD and brown noise absolutely helps calm me down… So that engine noise? Puts me right to sleep I don’t know what it is about it.
Also I usually smoke a bunch of weed before going to the airport so that helps.
