Isn't all this dream interpretation stuff a load of crap?

[Peter Eater]

Correct me if I'm wrong, but no factual evidence exists proving that dreams can be properly interpreted.

There have been numerous books written on it, each one saying different things from the next. Many people claim they can interpret dreams, but each "guru" gives a different explanation than the other, and none of them have any solid theory to explain there work.

Is it just me, or does anyone else out there think that, because of this, all this dream interpretation stuff is a load of junk? If so, why is every 3rd question in Social Science about dream interpretation?
