Resumen
(ES) En el ámbito científico la ensoñación ha supuesto un gran misterio para los psicólogos y pensadores
desde hace 3000 años. La ensoñación se define como todo tipo de actividad mental que ocurre
durante el sueño y solo puede entenderse en el contexto del mismo.
Para identificar las bases psicobiólogicas de la ensoñación, se ha realizado un recorrido desde las
distintas fases del sueño, las bases biológicas, las diferentes teorías propuestas, pasando por los
estudios recientes, hasta llegar a las funciones y generación de los ensueños.
Se ha demostrado que los ensueños que aparecen durante la fase REM son de carácter más vivido y
presentan una narrativa, además, las áreas cerebrales que se activan durante este fenómeno son muy
coincidentes con las activas durante la vigilia, por consiguiente, se ha destacado el papel de la
dopamina en la generación del ensueño.

Dreaming is defined as any kind of mental activity that occurs during sleep and can only be understood in the context of sleep. In order to identify the psychobiological basis of daydreaming, a journey has been made from the different phases of sleep, the biological basis, the different theories proposed, through recent studies, to the functions and generation of daydreams. It has been shown that the reveries that appear during the REM phase are of a more vivid character and present a narrative, in addition, the brain areas that are activated during this phenomenon are very similar to those active during wakefulness, therefore, the role of dopamine in the generation of reveries has been highlighted.
