Sounds like a pretty neat metaphor—like a firewall that only lets what belongs to you through. Dreams do that in a softer way, yeah. They block out the noise, but they’re also generous with the parts that matter most to you, letting those subconscious threads slip into the waking mind. It’s a filter, but it’s also a doorway, just like a gate that only opens to the right key. And sometimes the key is something you barely notice until the dream is over.
