When you're blocked, here is a very simple trick that can unblock you.

Get inside your reader's head.

How? Wherever you are in your manuscript, whatever stage you're in, do this.

Print out the section where you're stuck.
Read every sentence, and after every sentence (or every block of the scene if you're in the blocking stage), ask yourself: What's the next question on reader's mind? What do they care about?
Read the whole section, line by line, while holding in mind these questions. Pretend you're the reader. What do you wonder about now? What about now? What about now? What's the worst you can do to the reader to make them wonder what happens next?

Tell me how this works out for you! It does wonders for me (thanks to my editor who taught me this trick).
