We've had a hell of a good time spending the past 6 years scrounging up weird science and history junk for you to listen to! It's been a privilege knowing there a lots of fact junkies out there like us, digging through our podcast like raccoons in a trashcan. Our legacy is 328 fantastic episodes and we hope you never stop coming back when you need a little weird and wacky in your life.
We'll still be on Instagram, full of shenanigans and making reels. Never stop being curious.
Love ya forever, Trace and Amy

How do we define and study the little voice in your head? Is it something you HEAR, hear or is it something you think? For some of us, there's no inner monologue, for others, it's so loud in there, it's hard to participate in the outside world. Trace fell down the research stairs on this one! It's a double header of things we hear and see in our heads. Get ready for anendophasia and aphantasia!

Transcript:
[00:00:03] Speaker A: Welcome to Brain Junk, I'm Trace Kerr
[00:00:05] Speaker B: And I'm Amy Barton. And today I'm gonna continue changing your lives because we've talked about how to up your personal hygiene game. And today I'm gonna tell you about why you wake up at 03:00 a.m. And give you some tips and tricks.
[00:00:19] Speaker A: To stop that from happening.
[00:00:21] Speaker B: Yeah.
[00:00:24] Speaker A: I am not a 03:00 a.m. Wake up person, so this will be interesting.
[00:00:27] Speaker B: You're not what it.
[00:00:29] Speaker A: No.
[00:00:29] Speaker B: Do you wake up in the night?
[00:00:30] Speaker A: No, I'm not a wake upper.
[00:00:32] Speaker B: Oh, that's interesting. Well, Chris and I both are, and I tend to. On a good night, I just wake up once. But oftentimes I will wake up in this somewhere between two and 04:00 a.m.. Time. And so we're both like, why is that happening to us? And some of it is Shelby the cat.
She seems to get the zoomies. So let's back up, too. Greg Murray, professor and director, center for Mental Health in Sweden, Swinburne University of Technology. Swin. Yeah, Swinburne University of Technology.
He's a psychology researcher, and his expertise is in mood and sleep and circadian systems. Oh, and so he talks about this in an article for IFL science. For those of you who don't wake up like trace, it's bad because in the middle of the night, all of the thoughts seem to be. It's never like, I was so good in that meeting today, and I just love these blankets, and it's not that stuff. It's distressing and punitive thoughts, and they're irrational and unproductive. If you are alert enough that you have awoken, usually some people, it might not be that way, but it's definitely the way my brain works. It will worry about everything and anything....
