Fantasy is good for physical and mental health.

Try to keep yourself busy, divert your attention, and don't always fantasize. It is speculated that you are under great pressure to study, and sometimes you want to let yourself go, but it is often so easy to form a habit. When you are upset or don't want to study, you will unconsciously fantasize or recall the past, and travel will be very vicious. Long-term is not conducive to physical and mental health. It is suggested to exercise moderately and take part in more active group activities.
