laravel sail deletes database

Hello, I am creating a project via laravel.build and setting up a development environment via laravel sail. The problem is that at some point my database just disappears:

SQLSTATE[HY000] [1049] Unknown database 'laravel' (Connection: mysql, SQL: select * from sessions where id = Ix7hHmuK9P41ecwnHp3X0vzdKKFD98qGt9IXC05v limit 1)

It usually happens when I step away from the computer. Literally an hour of idle time and the database is gone. I can of course run the migration every time, but I'm still wondering why this is happening.
