AIO? roommate calling peeps loudly past 3 am

my roommate who lives in the room right next to mine calls her family who lives in another country past 12 am and sometimes past 3 am EVERY SINGLE DAY. i can hear her screaming, laughing, singing, all of it super clearly. it messes with my sleep. the walls are so thin. i'm annoyed. am i overreacting by being too sensitive?
