I certainly don't go for the idea that dreams try to tell us anything. For example, the crashing aeroplane thing is supposed to represent fears about sexual performance... so why does the human brain visualise it as a crashing aeroplane - for everybody? Firstly, that's a ridiculous suggestion regarding human brain development (what did we dream about before aeroplanes existed?) and, secondly, if the brain thinks it has an important message to tell us why cloud it in obscure messages only fathomable by 'experts'? Just tell it like it is, I'd say.
