بسم الله الرحمن الرحيم
(Fatwa: 259/222/L=04/1435)
These are satanic dreams. You should recite Ayatal Kursi and four Quls before going to bed and blow on your hands and pass your hands over your whole body. Do this thrice. Also try to go to sleep with wudhu and lay on your right side facing Qiblah.
Allah knows Best!
Darul Ifta,
Darul Uloom Deoband
