Someone comes to my window at night to watch me sleep or something. I pray and sleep with my window open and noticed them try to pull my curtain away. [Spirituality & Religion]

It happened a few times. Once i saw a man jst outside my window at 2am. Last night someone tried pulling my curtain aside to watch me. I asked whos there and they ran. They dont steel anything, they jst watch me sleep or something. What to do?
