I listen to a classical music station as I sleep and a lot of times the music seeps into my dreams.
I remember one dream not too long ago when I was on stage singing Con Te Partiro With Andrea Bocelli. I sang it in an entirely different language along with him.
In the dream I also understood what I was singing. But upon awakening I couldn't remember what thought the lyrics meant.

Funny how the mind can trick you like that.
