Dear fellow members, Thank you for the present debate on understanding the human brain. Could I test your patience with a couple of light hearted observations; you see I have just had a brainwave. I dreamed a dream and out of that dream, which took me all over this world at no cost and into realmes of the mundane ( my everyday existance ), I had an awakening Question. What real business is my brain up to? Are dreams play time for the brain? Complex dreams are busily being composed and stressed over by an agitated chemical process, or maybe neuron activity is involved. Why? Is dreaming part of the work of the brain? If so, where, or what, or who are dreams directed at? What useful purpose do they serve? I am not asking fellow members for posts here. Nor am I asking members for answers to my questions. I am making observations that certainly point to the difficulty in understanding the human brain. westwind.
