ANSWER:
There’s no such thing as ghosts. There are jinns.
What you feel is a form of paranoia and you must put an end to it before you become a full fledge mental patient.
Jinns intimidate whoever is afraid of them and they are afraid of whomever doesn’t fear them.
Knowledge destroys these bad feelings that are inflicted by Satan who is trying to make life difficult for you. The jinn have no power over you and you must have your full trust and dependence on Allah. Make ruqyah over water and drink a lot from it until this goes away.
Maintain your daily adkar and you can also do ruqya.
PROTECTION: You must maintain your 5 daily prayers on time without fail. Fix a time for reciting Qur’an everyday.
Maintain your daily adhkar of morning and evening, before going to bed, after every fard prayer, while entering the washroom, while going out of the house, before eating etc and this will act as a shield against everything evil with the Mercy of Allah. You will find these duas in a booklet called ‘Hisnul Muslim’ or ‘Fortress of the Muslim.’
RUQYA FOR CURE: Do ruqya on water, preferably zamzam and drink lots from it throughout the day and night and also bathe with this water until you’re cured by the will of Allah.
