Sallam

Walaikum Salam

Everything is not superstition. Be careful. Where do u live?. Although i would say you shouldn't attach much importance to it but things happen these days. It is said that Prophet(saw) dislike narrating bad dream. Thats why "daddy" didnt want to tell you. So just pray. You dont need to run to Alfa, pastor etc. You can do this on your own. I know it's scary. Same thing happens to me be odun marun seyin and it came to pass.

Try to wake up early before fajr. Offer some tahajjud (naflat). After praying Subuh, recite the first 10 verses of Surah Khaf every morning. Inshalah you will be relieved. Someone is watching you. Even after u are relieved, dont stop reciting Sura Khaf. After Ramadan is over and 6 Shawwal, try to fast every Monday and Friday. Hope this helps. You may want to stay indoor in most cases or go outside when it's extremely necessary.

Good suggestion you got there.

Plus before you sleep, when already in bed, recite Suratul Ikhlas (Qul huwa llahu ahad ...), Suratul kafiruun and suratul Nas. May Allah protect you.

Wahaleikum salam brother........

I would like to add little more to the above suggestion. I used to have bad dreams before, Alhamdulillah it's better now. My brother told me about Surat Bakorah verse (1-5), (255-257) and (284-286) after fajr prayer and before going to bed. With the faith that Allah's protection can takecare of any evil.
May Allah protect you brother.
