In my opinion, the best way to approach writing a scene like this is to imagine it first. Imagine what is happening. The question says there must be a "suspenseful moment," so think of some situation that would be very tense and dramatic, something like a life-or-death moment or a heated argument. Now freeze that moment in your mind and look at it. Describe where your characters are, what they look like, and what they're doing in this moment. Your question also says to incorporate elements of the supernatural into your scene. Think about what that means to you and what supernatural elements might be included with what else is going on. I think once you get your imagination going, you will be able to picture it perfectly. Then you just have to write what you see in your mind's eye.
