i dont think its dajjaal, maybe some other evil spirit. what you shud do, like the others say, take a fresh wudhu, read surah kahf, recite four quls and ayatul kursi every morning, perform your five daily salaah's on time, keep good company and trust in ALLAAH to protect you.

also dont listen and involve yourself in music coz its haraam and doing it will make ''dajjaal'' proud of you.
