I'm currently learning Japanese (みんなさん、こんにちは！), and I've began noticing myself doing the oddest thing while listening to Japanese.
I sometimes find myself uttering back sounds I hear; even when I don't know what's being said. I don't know why I do this; and often don't notice for a good bit.
Something like: "ee watashi wa kono geemu ga atarashii to totemo tanoshiku asobu geemu tte omoimasu ne!"(ええ、私はこのゲームが新しいととても楽しく遊ぶゲームって思いますね！)
Would be uttered back as a vary subtle and hushed: "ee... ko, k-ko no... ee... ata.. atarashii... ee.. to.. temo... tano... aso.. bu.. te... n-ne..."(えー、こ、っこーの、えー、新しい、えー、とー、ても、楽ー、遊ー、ぶ、てー、んーねー)
Am I just weird? Or is this normal? As I've heard people learning English doing something similar; murmuring back what's being said; subtly; without really understanding what's being said.
Is this a thing? Or am I seeing patterns where there are none?
Edit: For the curious; "ええ、私はこのゲームが新しいとても楽しく遊ぶゲームだって思いますね！"(the above version is riddled with errors...) means: "Heh, I think this [game] is a new and vary fun to play game!" with the listener being expected to agree.
