every one knows about jinns but a few people dont believe on them.Actually i believe in them because of Islamic view point.almost jinns are present between us but we are not able to see them because they are invisible but sometimes they gives symptoms of their presence.
Actually once in my room at 3:00 am i feel that someone is behind me i suddenly turned to see but there was nothing and i was alone in my room omg then after 10-15 mins i heared my sis voice that she is calling me. but when i saw in her room then she was sleeping.
