Sometimes when I'm lost in thought a sound, a voice or a piece of music that I heard recently is almost completely reproduced in my brain, like I'm actually hearing it again. It's a subconscious act, I don't think I've ever been able to will that sensation consciously, but once it happens I can sustain it for almost a minute or two (especially music).
I have a very "strong" internal monologue, talking to myself all day. I supposed there could be a connection.
Anybody else have similar experiences?
