I have a itsy bitsy spider problem?

Right now it's night time. And I discovered small spiders in my room. I realize they swoop down upside down on their web and i have to kill them. I see plenty up my ceiling crawling and i believe there is even more. Right now should I sleep in my room? Because I think my room is infested with spiders and they might make a big web and Im really terrified. How can I solve this problem? Or should I sleep in my room and put up with it now then wait till morning to tell my parents? They are small spiders but there is alot of them up my ceiling crawling.
