You must be the “heng” or lucky ones not to see ghost only when you’re very bad luck, then you will be able to see ghost and baby that is just born can also see ghost but one can never remember how many ghost you have seen.
What is a ghost? Ghost is just a thing that look just like us , just that they could do things we can’t.
Your Little brother shouldn’t be that scare of if they see your ye ye but it might be scare for your little brother to see “people” on the ceiling and as for your room in the last apartment, it could be some tragic happen to the “roommate” and the face could be not very pleasant =) thx for sharing too
