Totally! Lol. Sometimes for a long time hahah. The mind is very much used to useless thinking, it gets real uncomfortable in silence. So lots of weird things can happen after self-realization. Obsessively repeating the same, recent insight for a few days can happen, too. If there’s nothing to think about, music can take the place of thoughts. Eventually, silence replaces all thoughts and music, at times when thinking is not needed and is purely habitual.
