It was around the time she woke up each night.
Usually to answer the call of nature or say a little prayer before returning to bed.
Between 2/2:30 am.
She would usually wake up, then look out the window she leaves open for ventilation just next to the room door.
Maybe it was because she slept on her right side and the window was her first line of vision, but she always looked at it first. It had become a routine, she wakes up, looks out that window for a while, gets up, unlocks her door, finds her way to the washroom to ease herself and then heads back to bed.
This particular night however, immediately she looked out the window, she caught sight of a movement.
