Do not worry yourself, such things are common especially if a house has been left empty for a long time.


Jinn are beings that have been created by God just as humans and sometimes they co-exist with us without any trouble and other times not.


Islamically when you move into a new house Quran is played to ward off any bad/evil Jinn that have resided there whilst the property has been unoccupied.


As has been advised above, keep some Quran playing in the background at all times especially Surah Al Baqarah as this will keep them away and if unsure contact Fanaar about getting hold of tapes to play.


Whatever you do, do not get scared as the Jinn take advantage more of your fear, go about your day without taking notice of these things and soon enough you will see that everything should have improved.


Good luck.
