Hi Gaz,
It all depends on who you are as to the meaning of the purpose of dreams. Some scientists will tell you that dreams are simply a way for your brain to sort and sift through everything your brain has ingested during the day.

Others would say that dreams are your subconscious mind sorting through things that are worrying you. Others may have other explanations................ there are many I'm sure.
However, I think dreams have various meanings, but these thoughts are based on my own personal experiences. I have nightmares that always seem to have some kind of 'message' for me, albeit they are often obscure and the meanings are sometimes 'delayed' in becoming clear.

Others are definate premonition dreams. Trouble is, I only know they premonitions when they come true.

Then there are just the weird, oo-errr type dreams that I haven't got a clue what they are!

They don't tie in with any category that the experts talk about.
Try reading through some of my dreams in the dream thread. I have had soe really obscure ones lately that I haven't posted.............. although maybe I should have?
