Pay no attention to that man behind the curtain

For three nights I saw what looked like an arrow on the ceiling over a curtained window (or door). I assumed it was some sort of emergency indication. Finally on the last morning I was brave enough to pull back the curtain. Surprised to find a full patio out the door! Then I had to do a translate and found out the word on the arrow was just meaning this is the direction to face for morning prayers. Considering the odd red stain on the door, I’m not sure I’d go out there to pray or anything else.
