“If you suddenly start daydreaming in the middle of doing something… this means something.”
“There are 3 reasons…”
First…
your brain is bored… so it literally escapes reality without asking your permission.
Second…
you saw something small—like a song, a face, or a memory… and your mind said: “let’s turn this into a full movie.”
Third…
you’re not distracted… your brain is just planning a whole fake life, complete with conversations that never happened.
