I admit, I love dream sequences, both in writing and in reading. I love how surreal they can be (they help me get out of a rut because I can just be weird and get the words flowing that way), and how they can reveal things about the character/plot/world. I like to use them as foreshadowing as well.

But from reading a few threads here, I'm getting the impression that lots of other people don't feel the same way. So I'm wondering, do you like or dislike dream sequences in a story? Why or why not?
