The comic strip depicts a brain with a thought bubble above it, transitioning from a state of activity to a more relaxed state as the person falls asleep. The first panel shows the brain with a speech bubble, indicating thought or activity. The second panel introduces a person lying in bed, awake. The third panel shows the brain with another speech bubble, but with a different expression, suggesting a change in the brain's state. The final panel shows the person fast asleep. This visual representation humorously illustrates the process of falling asleep and the corresponding brain activity.
