When a vibrating particle flies through the air, it's constantly facing the player instead of the direction it's flying, but in the Java edition it's correct

1. you open a world in the Bedrock Edition

2.Then you build a skulk sensor near an animal or by yourself 

3.And then you make noises so the particles can fly to the sculk sensor and then you see the particles pointing at you instead of the direction of flight

As said before, the particles look at you instead of the skulk sensor
