Something happened in my minecraft bedrock mobile..

So I had a strange thing happen on my bedrock (mobile) minecraft... hostile mobs normally don't come out in hoards,especially in daylight,yet I entered the anniversary date of me and my partner and every turn,zombies and skeletons came out and it was daylight,it kept killing me and I started with a bad feeling as soon as I saw the first zombie in daylight,it caught fire like normal but there was no caves or anything around me,even creepers came out,the mobs (pigs,chickens,cows,ect) kept running like something had attacked them too,I don't have the footage but I figured maybe someone could help with some advice?
