Eli5: Why can’t we hear our environment while we are asleep?
In: Biology
Pretty sure you do, your brain just chooses to ignore it unless it detects something that might be dangerous. If it doesn’t hit a “danger” box it doesn’t alert you to it.
That being said, the reason I know you can at least sometimes is because I pretty much exclusively sleep with some type of media playing. And it’ll often “leak” into my dreams. I’ve been able to go back through my recently played lists and pick out things that 100% influenced my dreams.
I’m also a habitual “sleep through my alarm” person. I used a siren for an alarm for a while and it took me like 4 straight days of tornado nightmares and waking up 30 minutes late to realize I was quite literally hearing my alarm clock….and it inspired my dream to make a tornado warning followed by a terrifying flee from tornados.
