What should i do about my dads snoring!! Please answer!!?

My dad snores so loud at night and i am really scared for tonight! I didn't get to sleep for more than 2 hours last night! I went into his room and told him to stop and he just said i was imagining it! I wasn't imagining it cause i was wide awake and then he turns over and just keeps snoring! So i plug my ears and almost fall asleep and he does the loudest one yet and then i keep waking him up! My bro texts me but does nothing! I put the pillow over my head and it does nothing and i shut the door!Then after that i just cry for hours! Plz i have to go to bed in 1 hour at 1:00 a.m. so what should i do!!!!
