ELI5: How are we able to 'hear' our thoughts inside our heads?

How are we able to mentally listen to music or remember what someone's voice sounds like ect.?

Science has shown that the memory of a thing activates the very same neurons as the actual experience of that thing. Subjectively, you are able to distinguish the two. One of the characters in the movie Waking Life put it so aptly, "the brain inhibits the activation of the vividness of memories. This makes evolutionary sense. It'd be maladapted for the perceptual image of a predator to be mistaken for the memory of one and vice-versa. If the memory of a predator conjured up a perceptual image, we'd be running off to the bathroom every time we had a scary thought."
