ANSWER: 

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.’

Do Ruqya. Kindly refer to the following link(s):

It started one or two months earlier, I suddenly woke up and felt someone slowly rubbing his/her hand over my private organs and then I tried hard but i was not able to move and then suddenly all became normal, next two times i felt same type of paralyses in my dreams but no rub on my organs. Now i have been noticing 3-4 marks on my chest near neck like an animal claw hit.
