Hello nairalanders...just want to know your opinion on this, I might have happened to you before.

You will be in a congregation,where there will be noise and all of a sudden everyone will keep silent for no reason.
Or
You might be talking and jisting with your friends, and all of a sudden you guys will keep quiet for no reason, it's not as if anyone is coming or so... Many people say "IT ONLY OCCUR WHEN ANGELS JUST PASS BY "...
SO HOW TRUE IS THIS

pardon my typo.
