If you have a male relative ask him to give Athaan in the house atleast once a day for a couple of days, that should help.
In my family we had many experiences of the third kind, my sister is a jinn magnet at one time one Alim said there were 7 jinns in her house, and I believe him, she has been seeing Jinns since she was a teenager obviously on occassions. My niece who was only about 2 yrs old at that time used to get up crying after seeing something very ugly. After seeing many alims Alham dulilah it has somewhat subsided now. Many people might think we were imagining, but after so many experiences I find it hard to believe everyone was imagining.
About a week ago my wife and I heard a loud noise in our room, it was as if something came crashing on the floor, like a huge wall frame or something, when we looked around there was nothing anywhere in the room or house.
Often these things happen, but as long as it is not harming you there is no need to worry. Just recite ayatul Khursi in abundance.
