According to the laws of physics, electrical signals generate visible pictures if electrical signals are converted to electromagnetic waves (EMW) of the visible range (light photons of wavelengths between 350-700 nm). During dreams our eyes are closed, so the brain is isolated from visible EMWs of the surroundings, yet we can see visible dream pictures. It follows from the foregoing that electrical signals of the brain processes can generate visible pictures of dreams if and only if electrical signals are converted to weak, EMWs of the visible range (biophotons) in the brain. Nobody can explain origin of visible dream pictures if only the laws of physics are being taken into consideration! The homeotherm state and REM phases of sleep are developed simultaneously in evolution. In homeotherm creatures there appear well-regulated body and brain temperatures, restricted neurogenesis, and well-structured neuronal systems, which bear a relationship to the holograph-like operating mechanism of the brain. Exact temperature regulation is important for many holographic systems, because holographic pictures can be deformed if temperature fluctuations are too large. A structured neuron system is also needed to develop explicit memory, because it can guarantee a strong synchronization of different electric and biophoton signals. If dream pictures are generated by biophotons in the brain these processes also have to work during wakefulness. Dream pictures make a connection possible between the explicit and implicit memory systems in the brain. Dynamical series of pictures can carry unambiguous meaning which can be a base of development of words in different languages. The human memory can operate through dynamical pictures, and we link these pictures to each other in the learning process. Neurotransmitters, which play role in neuromolecular processes, also play a role in thermoregulation and in sleep/wake cycles. So, neurotransmitters and synapses are hardly units of information storage. It is proved by in vivo imaging that spontaneous ultra weak biophoton emission from a rat`s brain correlated with cerebral energy metabolism (thermoregulation), EEG activity and oxidative stress.
