i got a few stories yang maybe too long to story here. but one personal experience is about my father. he was in the army in the engineering kor and always in the hutan. so he has a "pendamping" . so when growing up, sometime my father will wake me up to go to school. to mandi and all. but in reality my father would be on the other side of the country. my mom would be so angry if i'd tell her "eh ayah mana?" after a few times i finally understand whats going on and when "he" wakes me up - i can never see his face. its always someone that looks like him and he's always turned around his back to me after he wakes me up from sleep.

yes. but very little. bangun bangun. thats it

yea pagar. not in the physical sense. yes this one normal lah. but if someone hanky panky or drink / eat haram stuff in the mosque the pagar can get weaken.
