QUOTE : Man needs dreams, as recent sleep research has well-documented. If you wake people up each time they start to dream (which is revealed by their rapid eye movements, which has led scientists to speak of REM sleep, meaning sleep with rapid eye movements and dreams), they will, within a few nights, become neurotic, irritable and slightly paranoid. No reputable researcher has continued this experiment for more than a few nights, because the evidence indicates real risk that the subjects might actually go totally mad. It doesn’t matter how much sleep they have had; if they aren’t able to dream, the same neurotic and near-psychotic behavior will appear.
