Explanation

A ceiling is the upper surface of a room. If you’re lying on the floor, you’re staring up at the ceiling. If you’re lying on the ceiling, you’ll be lying on the floor again soon. You may have heard the sky’s the limit — but in truth, the limit is the ceiling, both physically and metaphorically. The top of a room, but still under the roof, a ceiling is the point at which you can go no farther. You’ll find both helium balloons and hot tempers hitting it. In the workplace, if you aren't getting that promotion and can't understand why, you might have hit a "glass ceiling."
