It's very possible. It is similar to when you play a game for so long that you can turn it off and actually hear the themes in your head, perfectly. I had it happen a few years ago when playing Pokémon (who'd guess) and I heard the HG/SS gym leader theme as I was walking around my house. It was a bit strange and I had pulled two solid all nighters while playing it.
Yes that would be most wonderful!
I love making new friends and I can't wait for us to talk more :3
Other person, that Charizard is amazing. Did you draw that?
I don't know how to tag, apologies
