hi, in our religion, we cant see them but like i was saying there are good and bad ones, some our muslim some not, it depends, some try to hurt u, they can come inside your body, they also can be in our homes, like if we want to have sex, we say bismallah, they will go away, also they like dirty places, like trash bins, and bathrooms, we dont talk whilst in the toilet, there are other things as well... some ppl swear they have a jinn inside them.... i dont know that much to be honest but im sure if u google jinn u maybe find better details:) there are some ppl also , it as something to do about a mirror, i cant remember but they think they reflect of something i dont want to tell u anything wrong so i need to ask a lil more..
but they can move things, and such, cut off lights, etc...
