:sl: aw sis firstly please don't be scared. Such whispers are from the shaytaan. Play/recite Surah al-Baqarah in your house at least every three days. The shaytaan flees from the house where it is recited.
Recite surah an-Nas, al-Falaq, and ayatul kursi over yourself morning noon and night when you retire to bed.
I have been experiencing strong whispers for years. Some warn me about other people/danger and some are downright evil. I use ruqyah but that's because I was advised by a raki. If I stop I suffer. If it is only whispers you are experiencing, inshaAllah what I mentioned before should suffice. :)
