why oh why oh why

am reading along, everything going great, and then Boom dream sequence.

I hate dream sequences (obvious exception being my awesomely current favourite movie The Science of Sleep), but why, why, why, why, why do authors put dream sequences in their stories? It seems to be happening more or more or I guess I am drawn to books in which it happens more and more. What is the purpose of a dream sequence? To demonstrate something in the character’s subconscious in a round-about-way? Couldn’t that be put into the text in a less oblique way? Am I just jealous as many of my dreams involve me getting up and brushing my teeth and getting ready to do something dull like mop the floors?

If I ever write a dream sequence, remind me of this post, and then mock me mercilessly for being a hypocrite.
