WebReorganizational (Crick & Mitchison, 1983) This theory focuses that the brain requires memory consolidation to work correctively. Therefore, in our dreams, we are sleeping to reorganise and improve memory storage. This theory follows the concept of reverse learning – we dream to forget – meaning learning can be undone during REM sleep.

WebApr 1, 1996 · Crick and Mitchison have proposed that dream sleep involves a reverse-learning (or unlearning) mechanism by which the brain eliminates internal parasitic modes from memory and avoids the overloading catastrophe. We perform stimulations on the Hopfield neural network to test this hypothesis. In our dynamical model, the neural … Reverse learning is a neurobiological theory of dreams. In 1983, in a paper published in the science journal Nature, Crick and Mitchison's reverse learning model likened the process of dreaming to a computer in that it was "off-line" during dreaming or the REM phase of sleep.
